Really cool and unique puzzle game! I love all the different mechanics and how they interact with each other. Very well designed as well. I was so happy when I thought I had discovered cheese when I started intentionally putting the checkpoint in the spikes and moving it while dying over and over again, and then I found out it was intentional, and then negated by the life system. My only real complaint is that the music is very monotonous, and got annoying really quickly.
