CrazyBirdie if it crashes that would suck... But there shouldn't be any crashes if there, and its related to my mod, let me know so I can fix it.
There are a lot of ways to tell if the video has been cut or edited one being the credits and ftl fuel amounts, frame skips, and the AI behaviors (in case they think they are clever and change difficulties)
But to answer your question there is no perfect solution to stop cheating but I am trying to make it as hard as possible to cheat.
As a side note anyone good enough to beat this isn't going to risk the run by attempting to cheat the amount of effort required to cheat this isn't worth the reward IMO which is why it's only a $20 bounty and not a $50 one like I wanted to do.
