YESS I BEAT IT!!
If this was your first ever game, this is amazing for 48 hours! My favorite thing about the game is the overall atmosphere created with the uncanny music and pixel art.
Even though the game is short, I thought it's a pretty good adaptation of the Parasite film, and looking at the time mechanic so you can understand their routine is a great touch. I think other people have mentioned some possible improvements, like having better player feedback for being able to place water anywhere, and that you've successfully placed the poison in the drink. Another issue I found was the guy would sometimes duplicate. Overall I thought this game was really well done and well scoped!
