Pros:
- Cool art style. The enemies look rather cute.
- Decent amount of variety in items/levels and randomness between runs.
- Music and SFX match the aesthetic of the game very well.
Improvements:
- Perhaps add the option to jump using the w key (rather than just space which is more awkward).
- The font used for the text in the cutscenes is very hard to read. I'd suggest using something like m5x7 or monogram as an alternative.
Bugs:
- I think theres a bug with the jumping. Are you supposed to be able to double jump at all?
Overall, good submission. Well done!
