This was fun! I enjoy the art and animations, and the intro was funny! Background music was great, also appreciated that it changed subtly after the tutorial.
The one minor point that was a little off is the changing directions of the game; I spend a whole level running in one direction, so when I move to the next floor, I accidentally run back towards the door I came from. Not that it's a huge deal since it doesn't take you back, but it's a bit jarring. I don't know the best way to mitigate it though, maybe if there was a larger break between levels or a physical staircase that you need to press the opposite direction on maybe?
Not a big deal though, cool game nonetheless!
