Thank you so much for supporting my game!
Basically, I realized a bunch of stuff was BROKEN. Steam is a little finnicky with my game. Anyway, the game should be stable now, and Achievements and save data work fine now.
Thank you and enjoy the game, wherever you're playing from.
F.A.Q.
Q) Some of the tiles have no number. What does this mean?
A) That is a safe tile. It will not tell you the number of adjacent tiles. Using tags to give you the ability to use more clue tiles are available.
Thank You Update (1.0.01)
