Satisfying shooting! I liked the character art, especially that they looked in different directions.
I realised I could shoot infinitely by holding LMB and RMB, and there was only negligible knockback. I wonder if you could do something interesting here to make not shooting a reasonable choice? For example Luftrausers heals you if you don't shoot.
The enemy health was just right for the mobs, they weren't a push over but you still got to feel good because you survived even after a lot of them chased you.
