Gravity Glitch: Break a gravity (purple) cube right before you walk / jump / fall into it to keep the reduced gravity effect.

Break cubes quickly: Bind break block to the scroll wheel in the settings.

Clipping: You can clip into two block high windows because the hitbox of the cubes has rounded edges.

Cube Stacking: While standing on a block, jump backwards, place a block and hold forward to land on it.

Jumping four blocks high (FPS Limit only): Use one of the tools found in the resources section of the leaderboards to limit your fps to 2. You can remove the limit right after you jump. 2 fps is faster than 1 because the game speeds back up to 60 faster.

Jumping on Save Points in any%: Limit your framerate to 50 (this is still allowed). Then press space twice and hold the second one. Limiting to 50 is still allowed so that people who have a bad PC and only get about 50 fps don't have an advantage over people with a better PC.

Save Glitch: Resetting from the location of a secret allows you to pick it up the frame after resetting.

Cube Placement Glitch (CPG) (Version 1.2 only): You can place a cube on another cube if you place it right after you break the other one. It'll disappear after a short amount of time. This can be used for the next two glitches.

Cube Storage: If you do CPG and place the cube back down, you'll place them both at the same time. The game doesn't check collision for the other cube. This means you can create chains of cubes through a wall or on a blue cube that's on an activator.

Teleportation: If you jump on a cube you used to do CPG before it has disappeared, you get a very high velocity towards the coordinates 1000, 1000, 1000.
