Nice prototype.
I know this is a just a basic prototype, but I hope you don't mind me leaving some suggestions:
- Make Mumei shoot faster but deal less damage. Seeing lots of projectiles go pew pew pew makes for a more exciting action game.
- Add a health bar to enemies or make them change color when about to die.
- The game closed when I died. Having a retry button would be much appreciated.
Keep up the good work! I hope you can flesh out this project in the future!
