This is like I Wanna Lockpick but reversed, really liked the concept! Utilizing the 'one key at a time' rule at the last level was very clever. I wish the puzzles had less red herrings though, but the game was still amazing.
I wasn't familiar with that game, played it a bit and it is very similar :D I wanted to add more mechanics but I figured i would run out of time, so I've focused on the keys and doors.
