You are a rat. You must climb.

Cheese and glory await!

In Rat Climber, you only have one goal: reach the top of the world.

You must navigate vertical labyrinth zones and make daring jumps, but be careful; one false move and you go tumbling down.

Three different modes

• Beginner:

  Checkpoints menu enabled, allowing for custom save-load checkpoints, as well as three specific world checkpoints. Play at your own pace and learn the path up, one step at a time.

• Normal:

  The normal Rat Climber experience. Checkpoints disabled. Achievements for reaching the end of each world enabled!

• Speedrun:

  For speed-runners, or those wanting to practice a specific part. Checkpoints menu enabled, as well as superjump, which basically allows Ratty to fly.

  You also have access to the level-specific restart option, letting you restart at any of the 12 zones across both worlds.

Two different worlds

Play through two different worlds for twice the rodent fun! 

• Ratty's World: The original seven Rat Climber levels

  Seaside Village, Crystal Mines, Cypress Swamp, Ancient Egypt, Mystic Towers, Cloud Temple, Shadow Castle

• Dream World: Five more bonus levels in a separate world

  Kraken Cove, Tempest Tavern, Playground, Foggy Fortress, Lush Ruins (with more in the future)

Secret cheese

There aren't hundreds of collectibles for you to worry about, only a single secret cheese per level, well hidden and off the beaten path...Can you find all seven?

Every object has 1-to-1 exact collision

If there's a small gap between objects, you can probably fit through. A 3 inch ledge? You can stand on it, Ratty! Building ledges are the highways of the rodent world, as they say. Start thinking like a rat.

Helpful signs

Your Rat ancestors left helpful tip signs all around the world. They will give you useful advice and encouragement on your journey. Be sure to look for the golden sparkles!

Simple controls

- There are only 3 controls: Jump, dash, and walk

The dash lets you jump farther  

The safety walk prevents you from walking off of ledges

Built for speed-running

Rat Climber was built for speed-running! There are a multitude of speedrun tools built into the game, such as:

• Overall timer that starts as soon as Ratty moves and automatically stops once you reach the final spot at end of game and lose control of Ratty.

• Individual level timers (both split times and segment lengths) that automatically record times when you reach new levels, no need to manually start and stop your own custom timer

• Superjump (allows you to fly) [only in speedrun mode]. There's also option to disable this, so you don't accidentally press it and invalidate a speed-run

• Custom save and load checkpoints to practice hard sections or skips

• Restart at specific levels instead of the bottom of world

• Restart hotkey that must be pressed twice (prevents accidental restarts)

• Official Speedrun website board with moderators, rules, and runners!
