Spider-Swing: one-button swinging game. Hold to rise, release to drop, don't hit anything
Not my build. Someone made this for a weekly challenge I run and it's good enough that I wanted to put it in front of people.
One input, that's the whole thing. Hold space or hold your finger down and you swing upward, let go and gravity takes over. You're chasing the Green Goblin across a city skyline while he lobs pumpkin bombs at you, and everything speeds up as your score climbs. Get to 10,000 and a Vulture starts making passes.
