Wow! It’s mostly working. Thanks a lot for sticking with it, I still don’t know why some of the audio files don’t load properly (and this time it’s 63 frames too few, weird!). Now that I know what kind of problems the audio can cause on some systems, I will definitely try and make the audio playing header more robust.
Yeah, that level is probably the hardest (that isn’t the intended solution), I think there’s only 3 more levels after that. There’s a full run through of the game on the itch page for all of the solutions.
A level indicator is a good idea, I somehow didn’t think of that. The light rays still have a few issues, like the switching on/off. The reason the goal takes a few seconds to “charge” is to stop these issues being exploited to win by shining a laser over it quickly. Definitely not an elegant fix!
