Real cool puzzle game, not often a lot of incredible machines inspired games :)
I like how you incorporated the physics based mechanics into the theme, instead of basket balls going through hoops its regulating a heartbeat.
Visually i like that you added eyes to some blocks and cells it kinda gives it a snipperclips vibe and it's also funny that they look wherever your mouse is.
This one's more on me than the game (not good at puzzle games ) so i didn't take it into account for rating but, i didn't get far XD i got stuck right after the tutorial when you have only the slope and single block and couldn't figure out how to have the correct flow, but despite that i still had fun and really dig its uncommon inspiration.
Good job :)
