description
This game is based on an art project I had been planning for a while, and then realized that perhaps an idle game was the way to go instead. It's also an experiment in vibe coding - it's about 98% AI-written code, albeit with me spending a few dozen hours writing the prompts and debugging, and I think turned out pretty well.
The game itself is a short-form incremental game that combines math and music to generate a song of epic proportions. Or at least of epic length. You'll see.
Currently in a beta build, please share feedback, bugs, etc. Thanks!

Fixed out-of-control endgame growth 0.2.1 November 12, 2025
Yeah, whoops, had some numbers wrong for the late game. Those should be a lot more reasonable now and no longer possible to grow out of control. The game is effectively over once you get the 16th prime, but you can keep playing if it makes you happy.
Also added a simple timer to count time spent playing.

very cool baseline, sad it's so short
I NaNed my factors and was unable to unlock the modulator :( I'd love more of this, actually ! More instruments, more scales... The ability to choose individual instruments for primes would be very cool.
developer response: Oh, individual instruments per prime could yield some interesting results! If there's enough interest for this to grow then that would definitely be on my list.
Game thats about things you can hear: must have sound on (optional)
Okay i know it doesnt say it like that but it feels like that.
Good idea for the game, has potential to expand. This is one of the times when too-fast progress is slightly bad. But, on the other hand, it is actually VERY good.
One issue, soft pad instrument is glitchy and lags the game too much.
possibly best gen ai game

Game breaks after 1.79e308 (I wonder why)
Even though this is gen ai, it's surprisingly good (atleast for my standards)
i like the concept it was fun kinda short though but would recommend
vibe coded lol
just goes to show that having the gen-ai tag doesn't make a game bad (still kind of a bad omen tho since it implies a lack of effort) 5/5 would NaN again
developer response: Definitely not a lack of effort - took me dozens of hours of work. I'm just a crap programmer, so the AI was writing the code as I was designing and refining the game. The intent was for this to be a "good" use of AI - one that is human mediated and finely-controlled. This was not "make a game that does this", this was "here's the full design spec, follow it".
Props to developer for adding next (OCD ppl like me)
