I have some feedback notes:
- When using assets from other people, you need to make sure they seem to belong the same game. The simple enemies don't fit with the detailed pixelart tileset.
- Most of the pixelart sprites are a bit blurry.
- You probably used one of the Music Jingles from Kenney's assets as the music, but I dont think that sound was designed to be a looping music.
- I would recommend adding some checkpoints in the game, so the player doesn't need to repeat a big chunk of the level every time they lose.
I saw this is your first gamejam, and I think is very fun! Keep participating in gamejams :D
