Jump Only

Jump Only lives up to its name literally, no run button, no dash, no attack, just a jump that has to clear spikes, traps, and sudden layout twists using timing alone, which strips away every other platforming skill except knowing exactly when to leave the ground.

Because there's no way to adjust mid-air beyond the jump itself, committing to a jump's height and distance before leaving the ground matters more than reacting once airborne, there's no correcting a misjudged leap in progress. Levels are short enough that memorizing a section through a few failed attempts tends to be faster than trying to react to each trap on sight. Level Devil runs on a similar trick-and-timing platforming format, just with more than one button to work with.
