Very cool game. While rough around the edges it was very enjoyable.
I got through the first level with not too many deaths. I did however have many difficulties with the boss, I wish there were more indication of where the fireballs come from. 

Overall, solid and playable, and I liked the intro cutscene a lot. Had a sort of 80's nostalgia vibe to it. 
Have a nice rest of the game jam!
