The sprite work, both pixels and high resolution, looks so amazing. Great interpretation of the theme, the setting and the use of pixel art really play into that retro feel.
The ice cream orders are a bit hard to differentiate sometimes. I also wasn't completely onboard with the lack of an interaction button, but bumping into things is pretty funny and didn't take long to get used to.
A shop between rounds to expand on the store or something like that could be a fun use for the money if you plan on working on this game after the jam. Amazing work!
