neat game. i like the simplicity of the controls, and i personally enjoy a good mashing game every once in a while, although there are definitely health concerns / accessibility concerns with that lol. (i think after a few rounds i would only really try mashing during the slower tempo parts, as there it feels much more like just tapping along to the beat than actual mashing).
the melodies when you drink the water properly are very interesting. i kept trying to get the next bottle correct so that the melody would finally just complete the scale and release the tension, but it seems they never do that. this is a neat way to keep driving the player forward... just one more melody, i'm sure it will resolve!
the polish in this game is super good. the way the curtains move back and forth, and the low-res "wetting your pants" effect... all just super effective use of the pico-8. good job!
