Awesome to hear such nice feedback. Thanks a lot for taking your time commenting :D
yeah, I'm considering a post jam version after fixing the bugs and doing some neat level designs.
My apologies for making it a little too hard Q_Q
Aye, the switching is a gradient shader changing alpha based on the current balance. Initially i thought of just having it become more dense as you run out of balance energy and just be the que for game over - can't see anymore, but then i played around with it some more and made it go full density, but then go in reverse, switching the color scheme and that looked really cool so i kept it
