The game is broken for me. The spiral doesn't work, and I can only move sometimes...? Like, at the start. I can press R, Z, and then move one square. Moving once allows the green thing to continue on it's path. I can move freely once there is no more path for the green thing to go over.
Game also won't move on from the "reached checkpoint sound" screen.
Edit: Works on Microsoft edge, not on google chrome
