I rated your game. I hope you can check out mine, too. (It's also my first Game Jam and I struggled with the short time) https://itch.io/jam/brackeys-4/rate/723470
Played it and left a comment on your page :) I did get stuck on the 3rd level, but I enjoyed the pixel art and concept. I also struggled with the timelimit (although I only started on wednesday, so that's my fault mostly :P ), next time I'd recommend trying to set some time aside for a little bit of audio, I think it could take your game up to the next level :)
Well done on completing your first jam! *hi5!* Good luck for your future games :)
