Release 22 is out

I have updated (again) wall jump and some probabilites for pickup and enemies.

Also, as most of the players were killed by traps, I made them a bit more noticeable.

There are still edge case to manage for the PR0T3CT0R (the one with the shield). You can sometime walk on his shield or get stuck while it is preparing its attack. Even if I have secured that a lot, I hope it won't be too painful. I will look into it.

Have fun !
