Your video was so enjoyable to watch! thanks so much for playing! Im sorry you couldn't beat it on the hardest difficulty, i haven't either to be honest... and i feel bad that you tried every level of difficulty to try to find a different ending when there was none :( im thinking about putting a note in game that mentions that changing the difficulty will not result in a different ending. At least right now it doesn't.
I hope it really was fun to play and thanks for pointing out all the bugs you found, that is extremely helpful!
