Hello,
Since a few weeks I’ve been speedrunning supertux 0.4.0.
We got it under 27 minutes so far: http://www.speedrun.com/SuperTux#Any_v0.4.01
Do not hesitate to join the fun and run against us!
If you do, be sure to follow the rules and record a video.
If you got any question you can ask here.
Do not hesitate to submit your run even if you don’t get under 30 minutes the first time, my first run was 1h40!
