Mod 1:
So, imagine that there are 3 types of collision tiles - normal, "red" and "blue". Tees can be "red" or "blue". If tee is "red", it can pass through "red" tiles and it can't pass through "blue" or normal tiles. But if tee is "blue", it can pass through "blue" tiles and it can't pass through "red" or normal tiles. Of course, it should be or not be real to change your "color".
I think it's a good idea!!!
here is just one mod now, but I believe that there will be much more.
