Things I liked:
- Strong connection to the theme
- Very good art, music, SFX and VFX (though SFX are pretty laggy, at least in the web version)
- Simply but addicting gameplay
Things that need improvement in my opinion:
- Enemy variety (at least any with ranged attacks), as most just run after you and do damage on contact and can be avoided easily
- Might need a couple more gameplay mechanics (for example, dodging would be great here)
