It's fun and relaxing until it crashes. And so far in my experience, it always crashes. After a little while of playing, it just inevitably freezes.
If it helps, the partial console log when it freezes is:
Uncaught RuntimeError: null function or function signature mismatch Pixel Game Jam 2024 (Aqua Theme).js:84

I can get the full log if necessary, but at a glance the stack mostly looks like a recursive animation frame/main-loop scheduler call chain.
