Navigation was really difficult - it felt impossible to tell where room transitions were since the edge of the screen is the same color as the terrain and the camera didn't stop at the edge of rooms. Movement felt fine enough - the gravity on the player jump felt a little too high but the dash felt really nice and was a lot of fun to chain with wall jumps. I think the controls were a little broken, it seems like you tried to offer wasd support but somehow the D key was bound to both moving right and junping. I was forced to use arrows for movement and space for jump which I don't particularly like that combination, I'd like to have z jump or wasd movement as an option.
Environment visuals feel pretty unfinished but the player animations are really well done. Music was fine. Fit the mood well enough but didn't really appeal to me.
