2 min crowling? It sounds wrong, it should take couple sec, it's only 30% slower than normal walking, so maybe it's a bug.
About cutscenes and alternatives with and without clothes, as I'm only working on this game in my free time, so reworking parts of it is just too much. I'd rather focus on getting it finished.
Currently there are 6 levels, you can skip them using cheat table and the next update will be when it's ready :)
