SpeedRun

A platformer maker built for going fast.

Make levels. Publish them. Race the world's ghosts on them. SpeedRun is a browser platformer + level editor where every level runs on one of 7 movement styles — and the clock is always ticking.

🏃 Seven ways to move

Every level's creator picks its ruleset, and each one plays completely differently:

• Classic — floaty jumps and stomps, the way you remember
• Precision — instant air control, wall-slides and wall-jumps
• Combat — sword swings, dash-kills, and spike pogos
• Dash Precision — 8-way air dashes, climbing, and dash crystals
• Momentum — build speed off alternating walls and never stop
• Auto-Runner — one thumb: jump, dive, kick off walls to turn
• Run & Gun — 8-way aim, auto-fire, turrets, gunners, and armored troopers

⏱ Built to race

• Live millisecond timer + gold/silver/bronze medal times
• Race the #1 ghost on any level's leaderboard
• Personal bests with ghost replays
• A Daily Challenge level, same for everyone
• Mutators — low gravity, ice, turbo, mirror mode, one-life, hardcore — each with its own leaderboard

🔧 Make your own

A full level editor with 30+ things to place: enemies, moving platforms, conveyors, warps, springs, ?-blocks, crumbling floors, switches and gates, lava, saws, firebars, thwomps, lasers, and more. Set the win condition (reach the goal, collect every coin, defeat every enemy), add a timer, drop checkpoints, pick medal times.

You must beat your own level before you can publish it. No impossible garbage — if it's on the board, it's beatable.

Then browse community levels, remix anything you find, and check the death heatmap to see exactly where your level is destroying people.
