I admit this game was confusing. I unlocked stuff and nothing happened. I had to unlock everything for anything to show up. I still appreciate how it was good as a puzzle game. Yes, I had to look at the walkthrough. It was just so weird.
I can still appreciate how unique it was. You didn't need much in terms of graphics. The design was fine. I don't know how that key randomly appeared. It just doesn't feel that rewarding.
