Stickman Climb! is a simple platformer thematically based on a mining setting. The player's primary goal is to help a light blue stickman character in a dark gray pot use a pickaxe to move across pink platforms and bypass obstacles until they reach a finish line that features a flag. Since the stickman doesn't have usable legs, the player must use the pickaxe and speed to help the stickman perform a variety of actions, such as leap over deep mine shafts and climb steps and walls.
If the stickman falls on sharp spikes or any other deadly objects, the game automatically respawns the character at the last save checkpoint marked by a green flag. If the stickman becomes stuck in a shaft, the player must respawn the character using a keyboard-based command.
With each win, the player unlocks better pots and pickaxes that they can use to improve the stickman's chances of progressing successfully through the game's many levels.
