I managed to get the key and to the door and outside!
This genuinely brought me back to early 2010's internet horror games, the repeated maze of walls and creepy childlike decorations really evoked memories of Slender fan games, FNAF and Baldi's Basics! By any chance were the chairs a reference to the chairs in Slender The Eight Pages or am I overthinking it?
I like the design of Mr Mc Prolapse, and the repeated robotic voicelines, and the fact he has no animations whatsoever and his AI is horribly broken.
This was a simple but neat little game, I think it could benefit from being less mazelike and a little more guidance as to what you're actually supposed to do. But for what's here I had a decent few minutes with it.
Good job!
