Game breaking glitches are terrible glitches that destroy the gameplay, sackpeople and even levels you have created!
Never loading glitch (PSP)
A common glitch that breaks your levels and makes you unable to edit or play your level and if you try to publish it, people will be unable to play it and they will have to quit the game.
Lock up glitch
If you move an item or if something breaks, the game will lock up and it will make you lose your changes to your level or corrupt your save data. Level load lock up glitch: This happens sometimes when you save your level by change to play mode. It will lock up in the middle of the load and turn off your psp. Once this happens, you will be unable to load or play your level as it will keep locking up. So then you will have to delete your level. This glitch also happens on the PS3 where sometimes when you're on the moon, it will freeze and you can't do ANYTHING. The only way to fix it is to turn off your PlayStation. If you didn't save, you will lose all your changes and possibly corrupt your PS3's memory.
