Nice work, as others have said, nicely fits the theme. I appreciated the sfx control options and dings feedback at the start. As others said, I found it quite difficult and couldn’t get past the 4th level. While changing difficult by changing the number of ‘touches’ definitely helps, I wonder if changing difficulty could also change other behaviors too (maybe higher jumps? Or on the lowest difficulty, grabbing the wall means you actually stick there instead of sliding down so quickly?). +1 to WASD from me too.
One other idea, took me a few times dying on level 1 before I realized the mechanic; maybe the counter could be animated or shake or something as you get closer to 0? and some kind of emphasis to show you got to zero on death, vs you just freezing. At first, I thought the game was ending because I landed on a specific tile that was dangerous or something.
