Vex is a stick figure parkour platformer that challenges you with brutal spike-filled obstacle courses across 5 progressively harder Acts. The original Flash-era Vex became a school favourite for its tight controls and satisfying difficulty curve — every death feels fair, and every cleared section feels earned. This browser version captures that same spirit with the wall-jump mechanic that defines the series: by sliding down a wall and timing your jump, you can launch yourself sideways and upward, reaching heights that would otherwise be impossible. Acts I and II ease you in with gap jumps and spikes. Act III chains moving platforms across wide chasms. Act IV introduces vertical wall-jump shafts lined with ceiling spikes. Act V throws everything at you at once. Checkpoints within each Act mean you will not lose all your progress on a single mistake, but the death counter keeps a honest record of every attempt.
