Defying gravity by kicking off walls to reach places a single jump never could.
Wall jumping lets players bounce between vertical surfaces to gain height, transforming walls from barriers into launchpads. The implementation varies wildly: some games require alternating between two walls (triangle jumping), others let you chain jumps off a single surface, and some add a wall-slide state that slows your descent first. The feel of a wall jump depends heavily on the kickoff angle, the speed boost granted, and whether momentum is preserved or reset. Get it right and traversal becomes a vertical dance. Get it wrong and players slide helplessly down walls wondering why the input didn't register.
Example
Mega Man X introduced wall jumping to mainstream gaming and it transformed the entire franchise's level design from flat corridors to vertical playgrounds. Celeste refined it into an art form -- wall climbing drains stamina while wall jumping doesn't, creating a risk-reward tension between conserving stamina and committing to risky jumps. Super Meat Boy's instant-response wall jumps enable the game's brutal precision platforming.
Why it matters
Wall jumping is one of those mechanics that fundamentally changes how players perceive space. Without it, walls are obstacles. With it, the entire environment becomes a traversal puzzle. It's a cornerstone of movement-focused game design and one of the most satisfying feelings in platformers when tuned properly.
