I'll think about changing textures but a lot of people said that it looks nice because they don't focus on textures but on jump that they have to do.
If I'd know how to make buttons which teleports (I'm not so good at mapping, I'm just doing it for fun) I will make buttons like <- BACK
SKIP ->.
And if you complete map there is teleport marked with "go back to lobby", so you can go back to choosing levels ![]()
