Level Devil, developed by Unept, belongs to the "trick platformer" genre — a format built specifically around subverting player expectations, where visible platforms might be fake, safe-looking floors might hide spikes, and the only reliable strategy is trial-and-error caution. That deliberately deceptive design philosophy shares DNA with games like The Impossible Quiz, just applied to platforming instead of trivia.
Games in this style rely heavily on repeated attempts and memorization, since first playthroughs are almost guaranteed to include several "gotcha" deaths — the real skill lies in remembering what each level actually hides once you've seen it once.
The objective is to reach each level's exit, but the real challenge is learning to distrust the obvious path, since the game is specifically designed to punish players who take things at face value.
Its devious trap design makes for a genuinely funny, replayable platforming challenge. GBK Games also has Fun Obby for more straightforward obstacle-course platforming.
