Guard clipping

Also known as: guard-skipping, guard-jumping.

Most guards can be skipped by run-jumping through them at a very precise point:

Level 1 (example)

Screen wrapping

Falling through a specific point in the level causes the Prince to "wrap around" the map and appear at the screen above.

Level 10

Level 12

Floor and gate clipping

Various techniques can be used to make the Prince "clip through" a floor or a gate that is closed

Level 5

Level 7

Level 7 (again)

Level 9

Fall damage crouch cancel

You can negate the "crouch wind-down" period that happens after Prince's two-story fall, by falling in a specific point (a corner between left wall and the floor).

Level 10

Inactive chomper glitch

You can make a chomper inactive by falling two floors and grabbing the ledge.

Level 9

Guard through-gate lure

You can make a guard advance towards you through a closed gate (exploiting a glitch that makes him think you're already on the other side of the gate for a moment).

Level 4
