Glitch
The game glitched me and made me start over.
Right after i stopped the room from flooding, I showed the mouse the cheese but nothing happened so i clicked the key again and it showed the same text, but this time i had no cheese so i went back to menu and loaded and died because i couldn't take the drains out since they were already out! Then I tried to get the key from the mouse again, but i didn't have the cheese... Royally Screwed and I had to restart. Please try and fix this.
