Want more cool precision platformers? Here are some of them I can recommend. In the spirit of Mobility!, I'll also tell you how difficult or accessible each of these games are. Have fun!
A precision platformer more focused around building momentum, and has a clear-all mechanic that's similar to Mobility's. It also has a wonderfully non-linear progression. Be warned, though, this game can get very difficult in the later levels.
A deep narrative and interesting platforming, where the health bar is replaced by a balance mechanism that influences your movement based on which kind of damage you've taken. Supports a wide array of accessibility options, including level skipping and invincibility.
Major inspiration for Mobility. In this game you don't jump, but flip gravity to get around. By Terry Cavanagh, who you might know for Super Hexagon. Supports invincibility and slowdown modes.
Minimalistic rhythm-based platformer, so platforms move and grow on the beat. Very psychedelic and generous overall, but with really punishing boss fights.
Auto scrolling levels in platformers have always been disliked for their difficulty, but Scrolling Survivor manages to deliver some of the best scrolling levels ever. And it's pay what you want, so feel free to check it out!
Super hard, music focused platforming game. Your signature move is the stomp, which will instantly ground pound you to the surface below you. With a techno soundtrack and music visualizers in the background, this makes it the game equivalent of a disco. This game gets very punishing later on, and has some adult content.
