Gassy GaoGao (archived) is a freeware platformer game. Its premise is about a farting dragon.
Speedrunning
This game is apparently so obscure, there is barely any gameplay footage online, let alone speedruns. This is also a problem as there is very little documentation for routing. To solve this problem, I started the Gassy GaoGao wiki.
Links and images alone are a bit insufficient for finding routes. I wrote a script to parse a given wiki dump into a visual chart.
