Thank you instead for checking out the game, it really means a lot that you had fun with it!! Oh and you're right- I totally forgot to write about the "Real" ending on the guide, thank you so much for reminding me! Just updated it!
And don't worry about the last ending, you technically already got it! So the thing is- the game intentionally breaks itself when you have gotten all the ending/death. It shuts down everything else and gives you an "exit" as a reward for seeing every content of the game but in reality, it's a never-ending loop of walking down the staircase hoping you're going to reach somewhere (waiting doesn't do anything!) so the final "ending" is impossible to get, and the only way to break the loop is to delete the game file and redownload to start all over again- so it's once again a loop. Sorry for the confusion and thank you for asking/sharing your feedback!!
