Thanks a lot for the feedback!! I am really happy you liked figuring stuff out, because that was the main gameplay pillar when designing this game :3
The only "problem" with that, conceptually, is that it requires a little bit of curiosity from the player, so I'm glad you had that spark! That's why I added the timer at the end (a bit of an afterthought, I must say) to exploit the other main pillar of the game; poop factory optimization! >:3 so I didn't even think of adding a scoreboard, but that may be a way of turning up that system an extra notch.
(Also yes, that lil goober is also my favourite; recording their sfx was also really fun)
