Hi! It took me a little while to figure out how to download and run the game, I didn't know you needed to download both files for it to work, but I got that figured out. The timer was really annoying. I ended up not finishing the game after finding four of the keys and then having to backtrack for a second red door and then running out of time. I think that taking out the timer would let the player relax and explore a little more. Some of the spots where keys can get stuck are also frustrating, especially if you've already opened a few doors and gotten several keys. 

I like this game! Great art and gameplay! Good job!

Please check my game as well ;)
