Really nice graphics, and an interesting idea for a game! Here are some things I'd add/change tho:
- Enemies should have contact damage
- You should be able to hold the left mouse button instead of only pressing to fire
- Some different items and enemies would definetly be nice (I know the time was quite limiting but still)
The rest was pretty nice, and the world generation isn't something I have seen (yet) in this jam. A nice entry definetly!
Anyways if you have time you could check out my game too! :D
