I have completed a very rough outline of what the Secrets run would be, I assume the time for finishing would be cut down to >45 minutes. The rules would be start when you launch Superhot.exe, and ends when you kill yourself at the end. You are allowed to re-enter the level (from level selecter) if you complete it but miss the secret. Also once we find out how to delete secrets the run will be able to be done with out the long "You have found all the secrets" note at the end. Therefore you would not have to have already found all the secrets for this run.
