Thanks for playing and great suggestions! I think I'll start pointing people to the two options: single click/touch or L+R mouse, going forward. I think opening up a keymap option for the toggle button will be best, and also letting you customize what you want the toggle behavior to be.
I'll remake the pause button into the "Level: X" UI box or some other box on the screen, in order to save some space.
I'll ponder some ways to up the toilet roll animation. I also really want to make a proper refill animation for that paper roll.
