This is neat and really enjoying it! Though admittedly stuck at level 14 and not sure if I am missing a fundamental mechanic to solve this one or if I’m just really dumb.
[Edit] I figured it out and it was because I was fundamentally misunderstanding some throwing physics.
For what it’s worth, captchas have been used for training image recognition “AI” well before AI became such a hot topic buzzword. Especially in the automotive industries - it’s why a lot of captchas are like “please select images that have a street light” or “bicycles”.
