I love the sound and visuals, they fit together great. Don't usually play games like this, but I had a lot of fun!
Flying enemies were a good touch, too. If you're planning to add more changes, here's a few ideas:
- Enemy healthbars (you get used to enemies being a one shot kill, but then they start tanking hits, this would help make that clear)
- Enemy spawn sounds (enemies sometimes spawn behind you and hit hard with no warning)
- In game tutorial tips for the controls (the jam page explains it, but most people don’t read that until after they mess up.)
