Sorry it took me a bit longer than expected to play yours, I ran into a problem and time is short so I hope I'm not too late.
The game is quite difficult but not in a bad way, the controls took a few minutes to get the hang of and understand exactly how it all worked and its an interesting take on the theme.
I loved that you allow for difficulty adjustment as I felt quite overwhelmed when trying to figure out the controls on top of dying pretty quickly.
Music is ok but I feel like there were better choices that would have fit in well with the game rather than a very samey loop, maybe experiment a little more in this area.
Art is pretty simplistic but its obvious that's mostly a design choice, it wouldn't make the gameplay any better of worse and the time is better spent in other areas.
