This is great! Solid puzzle design with clever use of spatial reasoning. The mechanic of equipping/unequipping the special ability, and the way it persists through death and combines with the respawn locations for puzzle complexity, is quite interesting.
I wanted a "restart level" button! Several times I made a wrong move and couldn't complete the level, and had to use b/n just to restart the current level.
Very impressive—felt like a full-fledged tiny game. I got some Braid / Super Meat Boy vibes.
