Nice game! I really liked the distinct visual style and sound design, and the puzzles were very clever. I am genuinely impressed with how many different puzzles you've jammed into such a confined space! Sudden deaths add intensity, but make the game a bit too repetitive for me. I also had what I consider to be a bug with the orange key: if I acquire it before getting the doorknob, it does not appear in my hand and I cannot use it on the door :(
Overall, great job! Thank you for the game :)
