Having the instructions wasd to move and then immediately having them janky was fun. Took me longer than I'd like to admit to get comfortable walking and jumping XD
Unfortunately for me the music is somewhat jarring. It was probably on purpose, but it was a little much for me. If it was intentional, one thing you can do to trigger that feeling without making it overpowering is to have a regular track that is more calm and occasionally does something unexpected/jarring, but not for a long period.
