Just a crasher, so don't tell me that is not fun. Ways of breaking scratch: 1 - Just uses the classic clones crasher methode, it's not rocket science. 2 - A forever loop in a "without screen refresh" custom block. 3 - The same as the one with 2 key but with more custom blocks that activate each others. 4 - Skips the Scratch's 300-clones-limit. 5 - Join the variable with a ton of 1s 6 - A define custom block that defines the block that is defining. 7 - The same as the one with the 5 key but with a list. 8 - Forever create a clone for forever create a clone. 9 - Create a clone for broadcast a message for forever create more clones. 0 - Forever add "list" to list.
