nice simple action platformer.
I definitely had trouble with the selected colors (probably because of a red weakness) but cranking up the monitors brightness to max helped me see - I still would recommend increase the brightness contrast between the colors - it should make it look better and more easily discernable.
I think the jumping felt fine, but attacking was very sluggish for a game that I wanted to play fast and basically never stop moving.
These small one-room puzzles were a great idea! I could see this being very cool if there was a time based leaderboard per room or sth.
Music was crazy good if it was made during the jam.
