Deep beneath, a chrysalis stirs... BIOTOMATA is a semi-active, sci-fi themed incremental with elements of strategy and story.
NOTE: KINDLY PLAY ON EXPAND/FULLSCREEN MODE, as this game is designed to take up most of the screen height! (Or not, if you enjoy your current aspect ratio, lol)
For new players:
I hope you'll enjoy the game! :D
For returning players:
Welcome back! Many new QoL updates have been added since the first launch, including:
- Endgame balancing: You now get more Embers to spend with each unlocked ending! A "Challenge Mode" toggle is added to settings to revert back to the original, more strategy-oriented balancing. This change is made to hopefully accommodate both the "I love numbers go up and becoming OP!" crowd and the "I love strategy in incrementals!" crowd <3
- Additional 25K starting mutagen upon reaching level 35 as an extra boost to ending hunters.
- New "Decimate" mechanic. One-shot enemies with 4x less combined stats than you with a single button click.
- "Auto-Decimate" option in settings to effectively reduce decimation to 0 clicks.
- Auto-use combat moves when ready by long-holding the move icon. (Should reduce early-game repetitiveness)
- Added settings option to show combat and reset formulas.
- Three moveset loadout slots! (Old moveset will need to be reassigned to account for new save structure, apologies in advance!)
- Instead of repeat clicks, you can now long hold the upgrade button to continuously spend Biomatter.
- "Double click to mutate" now has a minor confirmation prompt.
- Chrysalis now has icons which indicate which upgrades have been unlocked since last view.
- On mobile, scroll position of the cascade screen is now saved.
- Status effect tooltips on Moveset description screen.
- Info screen with updated credits.
I also hope you'll enjoy the game! :D

Wow. I came in here expecting another uninspired progression from "cell evolves into animal evolves into space, somehow". But what I got was actually a really engaging story! That's pretty rare for these types of games, and for it to play nicely too? Bravo. I liked how cutesy the achievement icons were and how they contrasted with the eerie, surgical icons of the organs.
developer response: > "cell evolves into animal evolves into space, somehow"
To be entirely fair, you're technically not wrong, lol
It is really nice to hear that you've enjoyed the game, and I'm glad you liked the ui/icon decisions I've made for the game :D
I gotta say something about this game.
When I started this game, I just thought it would be a nice short game that follows the life of a cell as it grows, with number go up mechanics and fun little graphics like Cell to Singularity. I couldn't be more wrong.
This game actually makes you THINK. You almost can never brute force progress, and everything is set up in a way where you can have multiple builds that all come towards the same goal. The fluidity is amazing, as well as the art, and the idle mechanics are exquisitely crafted.
And then there's the story. This story is the first idle game where I have genuinely felt chills during a game. The late game story makes you want to look behind you to see what monstrosity might be coming through your doorway... Everything builds to the perfect moment, and even though I haven't even finished the first ending yet (THERE ARE MULTIPLE ENDINGS), I know that there will be some horrifying moments where I'm absolutely heartbroken. This is the best story I've seen in an idle game ever, hands down.
Overall, amazing game, I will be playing it for years on end. This deserves to be a $5 game on steam. Thank you so much for making this. If I think of more praises I will happily give them to this game.
Also, is there a reddit/discord? If not this game needs one and I will happily be a part of it!
developer response: Thank you for playing and thank you for the review! It always brings me great joy to hear people enjoying the game!! I really do hope the rest of the game doesn't disappoint :)
There's no discord/reddit atm since I haven't been on social media too often and would likely not be too active/ be able to maintain them, lol. I do check reviews every now and then, though!
I finally beat the game, 4 times.
BIOTOMATA is an amazing game, I had much fun playing it
and yes, I play it during down time and when we're not doing anything, or when I'm done with notes and waiting for the next ones
developer response: Ayyy congratulations!!! Thanks for playing and I hope it made your school life a little less drab :D
how do i beat A.C.T 😭😭😭😭
developer response: You can beat them if you specialize in each evolution stage, or skip them entirely if you complete the safe room event in the final area
Yea I've lowkey just been on a grind in school
developer response: I hope you're mostly engaging with the game during downtime! You'd better also be paying attention in class >:0

Damn what a game. It might just be one of the best games on this site and I've almost played everything on here to completion. It's kinda funny coming from A Tale of Poop and Vengeance to this, though your knack for story telling kept on. On that note, the story is a very nice touch. I don't really expect an engaging story out of games like these, but I did really enjoy the overall progression with Daniel and I liked how I could slowly see where it was all heading as the game progressed.
The pacing is very solid. Like you said in the info, basically every part goes by pretty smoothly (unless you're deliberately trying to skip something or you're doing something wrong). The combat is very nice too. Early on, I felt that the Constitution Vitality build carried me through everything but as I did Ending runs, I gained a lot of appreciation for the other builds. It's really nice how everything has its own unique flavor. The battles are also varied and interesting too, with most having a purposeful gimmick for you to adapt your build towards. The variety of mechanics is also nice and the game introduces and paces them out well. The prestige system is also strong and I never felt like I needed to grind runs and that I always had the choice to go for longer runs or runs specifically geared towards different objectives.
I also enjoyed the challenge mode. I always had a feeling you could do some interesting shenanigans with the ascension perks and I'm glad there is a way to utilize them, though I think it is for the best that it isn't like this way in the main game.
Personally, I feel like this game would benefit from a Dialogue/Cutscene Log or an Gallery/Ending Viewer. There's a lot of tidbits you can accidentally skip over and it'd be nice to see some of the endings again without having to redo a run.
I think some people might also prefer for there to be a bit more automation. I found it to be fine since you could just skip past all the first stages later on in the game, but some more decimates or area wide decimates could be a good quality of life choice. It's also not a particularly long game, especially if you don't do all the endings, but that's perfectly fine by me. In fact, I really don't think it needs to be any longer. As I said before, the game feels perfectly paced to me. Though maybe a wider expansion of a challenge mode with greater perks could work if you wanted to release it on steam and justify a price tag.
All in all, a really great game and I hope you continue to make more.
developer response: Thank you for playing, and an extra thank you for playing A Tale of Poop and Vengeance before this! :P I'm really glad you enjoyed the story! Funnily enough, I'd like to think of A Tale of Poop and Vengeance as a distant prototype-ish cousin to BIOTOMATA, mostly with the "event-storyline" and "mechanics that support storytelling" aspects. Ngl I was genuinely and pleasantly surprised with the reception it got, and it's definitely constructive/encouraging comments like this one which gave me the confidence to pursue BIOTOMATA as my uni capstone project
Happy to hear that you found the pacing appropriate and the combat enjoyable! I think it's pretty cool that you went with a vit/con build, since I've seen dex builds being quite common with midgame! Glad that you enjoyed the rest of the mechanics too!
The Ending gallery is definitely showing up as a common request. I'll add it to my TODOs, though it'll definitely need a separate UI component of its own, hopefully I can get it to work! Valid point on the automation, I might experiment with the decimate threshold a little and see what sticks better :)
Hard to say where my gamedev journey will take me next, especially since I'll be graduating soon and may likely need to start finding some stable employment first. Fingers crossed BIOTOMATA will be a neat enough portfolio project and I'll be able to find something that's just as rewarding while still allowing me to continue gamedev in my free time!
Fuck this shit, I quit.
developer response: Oh come on, they're friendly I promise :)))
Also i just had to doodle this: https://imgur.com/a/NMMDHx4
Dude, I came here to play some bad TMT games, not to find one of the best idle games I think I've ever played. The writing, the visual style, the gameplay (for the most part) was all superb. It was a touch slow at times and had a bit of the learning curve, but the unfolding story and the puzzle-like aspects of the endgame made this incredible. Kudos
developer response: I am sorry, I will work harder to make a bad TMT game next time :'(((
Jokes aside, thank you for your review! I'm happy to hear that you found the overall experience enjoyable!
Tip: You can hold combat actions to auto-trigger them :)
developer response: A very pro tip :D
Edit: Oh, also, the "Space" key will quick pause combat!
Absolutely amazing game, i played it originally after finding it on r/incremental games, it was amazing then - i cant wait to experience it without the 42 point cap >:)
developer response: Thanks for playing the original version (and going so far as to play again)! Have fun!! :DDDD
