Lost in Space

I get to crafting room I basically kinda quit because of battery room requirements (would play if I have willpower to)

How to open battery room?

Just beat it, 7h 34m with 0 deaths.
It's fun, I really enjoyed it. You have limited resources and it really requires some planning and prioritization.
Expanded oxygen tanks is a really nice upgrade to get early since each oxygen refill still brings you up by 50% of max, so you get more out of each use. A couple of each efficiency upgrade is enough until the late game, then focus on solving puzzles (in a separate document to minimize trips).
Once you get through the early game (around when you open the battery room), it gets a lot easier to optimize resource usage - the upgrade which allows you to recharge energy wirelessly (first buy the one in the generator room, then the global one) is a massive boost to efficiency and needs to be prioritized despite the latter's high cost. Once I had the global upgrade (and had connected all my rooms to the grid), I opened the last 3 rooms and won without using a single oxygen tank or even using the oxygen room's refills because it's such a force multiplier - being able to make infinite items in a single click is massive. You can get all the efficiency upgrades in just a couple of clicks at that point.
Really fun, though. I like this sort of concept and progression. Good job.

It seems like all the stars will have lower energy when you mine them, and production is affected by energy left. It took a long time to get just a little bit of energy at the end.

Fun game, though you can kind of cheese or make the game easier for yourself by putting an autoclicker on at the beginning and grinding experience to effectively make oxygen a non-issue. Maybe make the experience gain time based rather than room based.

It's really annoying that clicking on anything, even if it does nothing, or even clicking on the background of the game uses up oxygen.

A little early for me to give a full judgment, but I admit that I am invested. I got really stressed out for a while, barely being able to keep going at times but finally making it to the Oxygen Room's door... Only to immediately realize I didn't have the resources to make it in without dying. Fast forward probably another half-an-hour of playing and I did finally succumb to the lack of oxygen. Now, this may be because I often don't read when starting a game for the first time, in a flippant, "Who reads manuals anyway," sort of fashion, but I didn't actually expect a prestige system and thought that would be the end of things. As such, I took that run very slowly, finding the game at times to be tedious yet rewarding with its system making every action precious rather than incentivizing me to just go fast. It's imperfect, as all game jam games tend to be, but man do I really like what I see here so far. It will take me some time (a lot of time because I'm not always focusing on it) to get further than I did on my first run, but I do get the feeling, what with this being a game jam game, that I'll be left at the end wanting more. And perhaps some refinement of the idea. But with the novel mechanics and fun design, this may become one of my favorites alongside the likes of other unusual incrementals such as The Junkyard and Peter Talisman.

I really like the concept, was hooked as soon as I figured out the basics. Tedious, yes, but satisfying.

been playing, its super grindy but i like it
one huge tip that will help you is CONNECT YOUR SPACESHIP WITH AN ENERGY GRID KIT trust me it will save you

dam it no longer loads in my pc and is just a grey / blue screen
