I enjoyed the graphics and music/sfx, it really captured the retro vibe. The four-colors rule was accomplished very successfully and never felt like a burden! I wish there was more of it to play, though I understand that game jams can make that difficult. I also think the platforming at the end could've been a bit clearer, though I did end up figuring it out, so perhaps a bit of trial and error was intended. Overall great vibes!
