The original idea was to procedurally generate the content of each room. Unfortunately, i didn't had the time to do this, because the dungeon creation alone took me too much time.
I get that the colors of the bullets are a bit too bright.
At the end of the jam, i'll think about whether i should develop the game further or not. I think the dungeon creation is very exciting and will use this mechanic to make a game with a different combat system and much more ideas. But as i said, i won't decide that until the jam ends.
Thanks for your feedback though. This helps a lot.
