Next is:
Sliding Skill
The problem is level 12. This level can not be completed because you start stuck in the wall up in the left corner. Have tried many times and same problem every time. The only version I can find is the Skid Row crack. So not really sure if this is a crack issue or a bug. For me it looks more like a bug.
You can
download the trained version and use the level-skipper to skip to the level to see the problem (savestate also attached). Would be nice to have this fixed
