A small game with a collection of various puzzles. You need to enter a 4-digit code using visual clues.

+ Nice variety of difficulty. Some levels are easy rest, some of them are very tricky.
+ Many puzzles use math or logic, but some require general knowledge (like astronomy) or working on metagame level.
+ In-game help that gives an additional text clue for hard levels; very useful!
+ You can skip levels and solve them later.
+ I was trolled :)
+ Achievement-friendly: no missable or hardcore ones.

= ~1.5 hours, ~100 puzzles.
= Most levels generate their code each time, so screenshots don't spoil answers. But, I think, there's no reason to replay any of the levels.

Just a one-time funny puzzle game for a wide audience.

100% in 1.5 hours. Game has nice puzzles, but nothing more. Fun like in an EXIT game, but cheaper.

fun time hooray hooray hoora
