Its a very easy puzzle once you get the trick behind it.
Ridiculously easy puzzles, and elements in some rooms were never used (such as the washing machine in room C, and the large darker rectangle in room B that looks like a safe). I didn't find the last hint for the arrows, but solved the game anyway. About 5 minutes to beat, virtually no sound effects, and not even any interesting graphics to make up for it.
only hint ill give is alphabet is numbers
I did it.
Everyone, who didn't, is stooped
I couldn't figure out puzzle B and couldn't finish the game. :|
