Brutal difficulty just released and I wanted to post a run but I don't know if I have to specify the difficulty or if the only runs accepted are in Violent difficulty.
At the moment you can run whatever difficulty you see fit, however the most optimal difficulties will always be harmless (For when there are no enemies or at least very few) or violent (when you have an arena or multiple arena's to clear) We plan on adding something for other difficulties later down the line, most likely when we get to 1.0 (Full game release)
If you have not seen ULTRAKILL is finally having a speedrunner competition for real money!!! It starts in about four hours from the time I am making this news post, in fact its probably already started when you are reading this so click the challenges widget on the right and read up on the rules and
