This is a really neat idea for a game! It feels a bit like surgeon simulator. Also, the audio and graphics are awesome!
The controls feel awkward, but I think that is kind of the point. It feels a bit like surgeon simulator.
One big thing I noticed is that I couldn't figure out how to close the game. If there is a close button, you may want to advertise it more. Otherwise, try adding one! The other thing was that it felt like the controls didn't always work insanely well. I would press W or S sometimes but nothing would happen. Also , when I tried to pick up toilet paper this one time, I couldn't pick it up at all.
Overall, your game is a pretty great game, and with some changes to the controls so they are more consistent, it could be improved greatly.
