Thanks!

I've uploaded an improved movement code, esp. the stair climbing was horrible which should be smooth now!
If you have stairs, place a block in WED below them with a "none"-texture attached and check Flag3. (Check Flag1 to activate the boy's crouching mode automatically). See my example level!


I thought we could use a single key, the context sensitive button, to pull crates, activate switches, switch players and to use potions. The problem is, you should always be able to take the reverse-gravity-potion and to switch players. I think we just should add another key for potions only, then we have three keys (jump, context, potion).
What do you think?
