I saw it on AlphaRad's channel recently. Coincidentally, I had been contemplating the idea of trying to make a speedrun of something, and WaveLand's demo happens to be absolutely perfect for speedrunning, since it's short and always leaves room for improvement.

Hi there! I created a simple autosplitter for the demo. Here it is: https://github.com/ishanpm/waveland-autosplitter I'm not going to try to add this to the xml, since it doesn't work with the full version (which I do not own; but plan to buy) and it doesn't autostart yet.

I'm probably gonna make a run with this once I get recording set up. Current best is 4:20.57! (any%, using the highly technical "Close the game to skip the tutorial" strategy)
