Fantastic game! I loved the creepy mood that the background music and the animations created. Puzzles were a lot of fun, I'm a fan of Cube Escape games and yours had a similar quality to it. I only got stuck once - where you have to rotate the valve, the puzzle itself wasn't too hard but I think I miscounted the first time and didn't realize I had to reset it before I tried again. Other than that, everything flowed really well. Very well done!
