I'm in love with the sound design! I feel like this usually gets ignored for jam games but it really, really makes this one. excellent art style as well.
The scoring is confusing though. Why shoot for a low score when I'm not playing against anyone or anything? I would almost prefer actual limitations, like only having so much to spend on a given level, or being given scores to work against (like puzzle games that give you a star rating depending on how many moves you finish a level in.) I also wish something told me what each of the puzzle elements did.
Loved it, and props to the "sound of something fizzling out" playing when you exit in a menu.
