Ok, I love the voice acting and the general vibe of the game! A little tutorial might go a long way? Even something very basic. I was unable to click around and figure things out my first go through as my cursor went off screen and I couldn't control the game anymore after that. When I reloaded I tried going full screen and that helped me stay "in game". The inverted mouse controls definitely threw me through a loop - I did not expect that! Something else I might say is the little windows/doors that opened when I hovered over buttons, most of the time they were cut off because I needed to have my mouse on the button and that dragged my screen down too far to really see what was inside.
Good entry, well done!
