Nice little entry, great job on your first jam!
You said that you wanted some feedback for improvements, so here are a few things that I thought of:
- I think the music needs some work, it felt really random and a bit annoying.
- When you rotate the player, the pivot seems a bit off, try to change the picot of the sprite so that it rotates from the middle of the sprite, the characters head.
- Screenshake! Always add screenshake!
But overall quite fun, congratulations on your first game jam!
