Hello, currently having a really good run lol, I know its very unlikely but is it possible to submit proof just as a screenshot or if the recording started mid-way?

Ah damn, ended up being a 41:04, oh well

Unfortunately no, screenshots do not count as sufficient proof. The reason for this is that cheating through save-manipulation is extremely easy in this game, so we need every bit of evidence for a run's legitimacy that we can get.
