The game is really good! I love how you used the prerequisite. I don't think it was necessary to show the available controls every time you die or enter a new room, since you have to wait for the message to disappear before you can play again. Maybe you could keep the controls visible somewhere in the room instead. I also thought the spikes were a little too big, but I think they mainly felt frustrating because I had to wait for the controls to appear every time I died. Amazing game!
