That's a cool game, congrats with your first project and the first jam ^^
I like the graphics, the main character looks very stylish! The music is nice too, sounds nostalgic and light (so you don't get tired of it).
The gameplay is good too, but I think the character jumps and moves too fast, so it's really hard to control him. Often I didn't even manage to see his movements, so even jumping at some platform was a challenge (or maybe I'm just too slow :D ). I know in retro-style (and hardcore) games move/jump speed is often high, but personally I would like a bit more time to react.
That's also a pity that you didn't try to fit in jam's theme, this game seems like something that would go together with "magical realism" good enough (if there would be some tiny backstory, for example).
Overall it's nice and fun. Keep it on! And again, congrats with your first published project ^^
