While being a relatively simple concept and having some simple gameplay the game itself with the visuals (specifically the character) and the background music honestly came together to feel a little... creepy. Something about the characters face and the music together just felt creepy slightly.
On the actual gameplay side though.
- The procedural generation of the platforms works relatively well, though since there's no variation and not really anything to worry about it becomes boring relatively quickly. Adding some more variation to either the platforms or possibly the background etc. could help.
- Movement is a bit disorienting due to the fact that only the background moves, or at least that's the impression given by there not being any extra catch up from the camera. Adding a possible lag in the code to the camera moving could help remove that.
- Controls the fact that S seems to make you faster and remove one of your "health" is quite weird, and unexplained in the game from my understanding. As well the fact that the "B" hotkey, which doesn't seem to impact the game too much lowers your health as well. Not to mention it's hidden in the wall of the control menu text.
