Oh my goodness, that was really really good! As many of the others have said, the camera is jank, but overall the concept really holds up. Its kind of like portal, but without portals, and theres a lot of death!
The lack of sound also brings it down a bit, but regardless of that, I left with the urge to play more. The mechanic is simply just genious.
Hit me up if you want help with the camera, or if you wish to get some music I also know a guy and two.
4/5, would play a full game of this.
PS. I forgot to praise your art, the character looks awsome!
