Really fantastic character designs, animations and music! The gameplay feels nice too.
The things that are missing for me:
- Definition of goal. Is it just endless procedural generation on the one map? Would be nice to know how to end the level (unless I just play until I die, in which case maybe add some tracking of "best run" or something).
- Some narrative! I want to know who these characters are and why they are doing what they're doing. They are really cute!
- Sound effects - it feels a tiny bit flat with no bullet, enemy, or collision SFX.
Great job on this, it has a lot of personality!
