Sadly the player is stuck in an endless loop which they can't escape. So the next level is only accessible by going into Unity and adding a portal and a next level which does not exist yet. The three hours ran out quite fast so we didn't get to making more levels. Next game jam there will be more :)
It is a bit buggy thats true. The way it is supposed to work: You click and hold the mouse button, when it hits something you get pulled towards it and when you release the mousebutton it stops pulling you and comes back to you. But thanks for the information, I will try to fix it!
