2nd comment, with more minor stuff.
Some issues:
- I got stuck just before the Freeze upgrade, because I couldn't figure out what I could even do next. I didn't notice that the upgrade was in a ball that rolled around. Once I saw it moving, it was a fun puzzle though. Maybe something could be done to bring more attention to the rolling?
- The purple box mechanic took a long time to figure out what was even happening. Maybe something could be done to draw attention to how standing in the right spot makes the boxes activate? Maybe the spot you need to stand on changes color when you're on it?
Some more cool things:
- The music was good!
- The "boss battle" at the end was fun and goofy!
Nice game! :D
p.s. Thanks for hosting the jam.
