The crouch glitch is a glitch that allows the player to make Karlson jump much further than usual. It is useful in every level except 12 ( I'll get to that in a moment). The crouch glitch can be performed by moving Karlson diagonally in any direction, Karlson will bend his knees and lower himself (crouching), then as he rises up you let go of jump and are sent flying in that direction. Many people already know of this crouch jump but, I recently found out that I knew something that some people didn't, that when you set the quality to fast and graphics to low, the crouch glitch has an INSANELY larger chance of occuring, I personally have no idea why this happens but it is useful, unless you are running level 12 in which having settings where the game looks better makes the run faster as in my testing I found that getting on the box was much easier with the higher graphics, quality and motion blur. Now obviously in a full game run you should have all low settings to make the crouch glitch happen more often. This will slow you down on 12 but the time save on the other 15 levels more than makes up for it.
