RUNTIME

Keep the momentum.

Chain dashes between floating crystals, turn the ceiling into your route and outrun glitches in a computer coming apart. RUNTIME is a precision platformer about reading the route ahead and finding your line.

Moving platforms and timed lasers put that line to the test. Checkpoints keep retries close as you learn each section and push for a cleaner run.

Race your friends.

Duel a friend online or in local split screen, then switch courses and rules for the rematch. Online Duels can also use Steam Workshop maps.

RUNTIME Multiplayer brings the race into the campaign. Choose chapters for 2–4 players online, race to the exit, then spectate anyone still on the course. For a solo rival, race a bot on Crystal Circuit.

Beat your best.

Chase medals and personal bests in Time Trials, revisit individual chapters, or take on the campaign against the clock in the unlockable solo RUNTIME mode.

Make it yours.

Mix unlockable appearances, headwear and companions. Explore for hidden discoveries, collect achievements and take on tougher movement challenges.

Build a course worth racing.

Lay out your next challenge in the level editor, jump into a playtest, then share it through Steam Workshop. Try community creations—or bring a friend and race a custom course together.

Play with a keyboard or controller. The free demo includes selected campaign chapters and official-course Duels, online or locally. RUNTIME Multiplayer, Time Trials and the level editor with Workshop sharing are part of the full game.
