Thanks you so much for playing, and especially for the footage. At the start I was a bit worried you would miss a lot, but it was very satisfying to slowly see you figure out essentially all of the game. I think the only thing you missed is that you can use right click to deselect. From the footage I could also spot a few minor visual bugs. Super helpful!
The logic for checking if a shape is inside is a bit flawed, since it really checks if it the shape touches the loop (and theres just straight bugs).
