Woohoo, a bee!
Pico-8 is awesome. Although I never finished anything on it, I learned a lot just by trying things. I use App Game Kit, and a lot of what I code on it I learned by coding on Pico-8. (I also tend to use its color palette too).
Your game is looking good. I want to try it when its finished. I really enjoyed the bee sprite XD
Good luck!
