Thanks for playing!
That is the plan, take it further, have more interesting environments, more mechanics and have an actual game!
Yes the inverted controls were certainly not intentional: out of the 6 faces in a cube made of 3d axes, only 3 work properly, the other 3 invert the controls. Something I want to fix.
As for getting stuck, i made it so It only happens on jump, to give more space because at the edge model is halfway in the wall. But after jumping if the jump height is small when you touch the wall, I would assume you get stuck.
