BIG NOTE: this glitches, as described, on my laptop (where I made the project), but not on my stationary PC (where the sprites never touch). Sprite1 touch Sprite2, but not the other way around!? Click the green flag and wait for iteration 60... Illustration of a glitch discussed in the studio Dads and Mums on Scratch: https://scratch.mit.edu/studios/25643089 Sprite2 is duplicated from Sprite1, and then moved 42 pixels to the right (just so they wouldn't touch all the time) All costumes are duplicates of Sprite1 costume1, a slightly offset circle. When the green flag is pressed, the sprites rotate 0.1 degrees CW and CCW, respectively. Green means touching, red not touching (see inside).
