Edge jump

Edge jump refers to the act of jumping to or from the edge of a block that contains usually freeze, teleport, or a kill tile. Edging these tiles is made possible because the hitbox of them is smaller than their visual appearance. The tee can go up to halfway into the freeze visually before they are considered in that tile. Kill tiles have a larger hit box, so edging them is much more difficult. See Collision for more info on hitboxes.

Misc Techniques

Auto edge jump

When using double jump against an edge and quickly holding the jump button down again, it is possible to automatically jump off of it right when you reach it. An example of a map that is designed around this mechanic is Toe Taps.
