Thanks for playing and the feedback! :D
I think I was only taking input in Update()
At first I was trying to use RigidBody.MovePosition() but that didn't work out well, so I went with addForce instead, so that I can move on and not get stuck at the beginning.
But after the jam I'll have time to experiment; so chances are, I may rework the movement System.
I'll be sure to check your game! :)
