well nothing to say, really!
Haha I would review it, but I don't really have any bad things to say about the game! The difficulty increses at a nearly perfect rate, the puzzles are addicting and you've got everything to make a game as popular as Sudoku!!
Only the music got kinda repetitive after a while, but we could turn it off and use ours so no big deal here!
Keep up the good work!
