Thanks for the feedback! I had a completely different idea for how to implement the theme at first--actual error messages in the scripts were going to appear as platforms that you could jump on. But early in the process I noticed that I had messed up the the raycasting for obstacle detection and, well, here we are!
Definitely some hints would be a good idea. My wife and my brother (the composer) both got completely stuck on one section until I told them what to do!
