That's the thing, there shouldn't be any guessing, because in a paper Picross game, you might make a mistake and not find out till later, by which time it might be to late.
Clever idea, but a big problem, perhaps a problem in most of your games, is you explain almost nothing. Is the story set, or is it completely different each time? How do the mood changers work? What is going on? Is the player supposed to craft their own story around the pictures? Is the color meant to affect this, or is it just an aesthetic choice?
I love this game, but the problem is, you never explain the game mechanics at all. Where exactly do the peoples' lines of sight cover, and how do the two-color blocks work? If you had explained that this is a strategy stealth game, not an action game, people would get it better.
-100/5 and you should get your internet licence revoked. You completely failed at everything in this one game. You transgressions were and are as follows: 1) A basic quiz game, with no innovation whatsoever. 2) None of the answers for the first question are correct, even though it is basic algebra. 3) To much gradient. Gradients should never, EVER be used to such a gross degree. A full spectrum is the exact opposite of subtlet. 4) Comic Sans? Really? What part of "Comic" do you not understand, retard? Even in comics, it's ugly and over-done. This font should be left to die, and it only serves to reinforce your gaudy, misguided, caffeinated-four-year-old design aesthetic. Go. Just go. Never upload anything to this site again.
