I didn't get a single right answer, damn kids with their meaningless slang! >:c
Okay, seriously, I really like the concept! The foggy effect with the glasses works wonders!
Only bad point: I didn't really find the gameplay entertaining.
If you look down, you have to take your glasses off, and if you look up, you put them back, so you almost always do C and G together (or you can listen to the audio and never look at the board).
However, the visuals and voice acting make up for it, it still was a nice concept, good job! =)
