Ok the tunnel works fine for me and for most of
the other people so i don't know how to help you
with that. (problem might be that you placed the
start position in the tunnel. When you do that
it is hard to not get it slightly caught in a wall)
I will not be able to make more stuff for the moment.
1 : I usualy take requests in my thread and not in others.
2 : I am involved in a 2d platform game with a couple
of friends right now (its a OPENGL thing and i make
some of the grafix.)
I will probably have time to make stuff later but
not right now. SOrry
