Great score, nice game feel and pretty cool idea. This game has a lot more polish than most others, but I'm hungry for more content. Great game nevertheless, and I hope this gets updated!
Only issue I had is that the jumping was a bit wacky at times, and I didn't feel in full control of the character's weapon. Other than that, it's nice. And nice work with the key binding! I found about it a bit too late... D:
