I liked the level design and the colored key-and-door mechanic. I didn’t fully understand the enemy AI, though — I hid in closets and under tables, yet they still waited for me as if they always knew where I was. Also, adding some music or a sound cue when the monster is chasing you would be really helpful (since it killed me while I was reading the first note and I didn’t even notice, lol). Overall, it’s a very interesting game with original graphics and character design. Great work :)
