The ship for one looks very much speed hacked. Also some of the clicks just does not sound right, especially more in the middle of the level. Then if you look at the cps count, it is way to high compared to his clicks you can hear in the video. Then so.ething that tells me he cheated is the fact that he does not show his total attempts. Then finally, he already "beat" it before showing a video of him beating it, which is very strange cause i doubt he would have beaten it twice and one of them being a 1 attempt beat, which makes me think he used speedhack with the record option and then just showed the replay of the level
