Really cool game! I like the concept of the controls being reverse in the lower region. It definitely makes for some mind-bending platforming as you have to work against your muscle memory. I mean that in a good way.
I ended up getting stuck in the level with the four columns of spikes. It did seem like the hitboxes for the spikes might have been bigger than they should have been? When I died and the game paused, the player wasn't overlapping with the spikes, so I'm not sure if it's a hitbox issue or the screen pausing slightly late.
Overall, nice job! The neon visuals alongside the ethereal music choice made for a very calming atmosphere, even when I kept dying on that one level, lol.
