Scroll left and right to rotate. The rotation will become movement. Click the bottom left corner to change gravity. Click the bottom right corner to change costume. Click the bottom middle to toggle mouse collision. You can also use arrow keys. Here’s a project based on these physics: https://scratch.mit.edu/projects/651020403/ .
One day, I thought of how when you turn one degree, you move opposite. Then, when making this, that’s when the variables were escalating quickly. 1.0:Release 1.1:More costumes 1.2:Improved collision except for lines(thanks @griffpatch)
