Thank you for your feedback! I did acknowledge the bug with the arrow keys, but I never got around to fix it. The next build should have that fixed, as well as increasing strictness for the hitbox.
I think it's funny how you've found the true and joke endings (which are the hardest endings to find) but not the other ending. Great job finding the joke one though! I thought everyone would play the game once and then brush over the entrance.
Thank you for playing!
