I thought this game was great, it was simple and fun but also made me focus on where my fingers were on the keyboard at all times, I did NOT get to the end because I felt like I went into every single room but just couldn't find them all. I don't think 12 keys is unreasonable, it had me wanting to play it until I beat it because the butler roaming around isn't difficult to dodge, but GOD I WISH I COULD RUN!!! Other than that I had a great time :)
