Bananas can fly through the gorillas...
Alas, while I made the update code twice the rate (60fps) of the draw code (30fps), it can still "miss" detecting the gorilla. 😇
If I had more space left (of the 1KB code!), I prob would've gone with a distance check, but I liked the idea (+potential pixel-perfect precision/fairness) of doing checking on screen colour.
My only suggestion when that happens would be to try to tweak the power/angle *fractionally* and hopefully it'll make contact 😉
