Interesting interpretiation of the capacity problem as a block puzzle (with fitting story^), wouldn't have thought of that! The colors create a nice, abstract picture :-}
Btw., any way to know how many solutions exist?

I liked the concept for the theme.  Would benefit from an ending screen as you mentioned in the game page and some audio would be nice as well.  Nice submission nonetheless.

Good (proof of) concept, you should definitely do a post-jam update with a “win” ending and a few sounds. Puzzles like this are big on mobile too!
