@Klamech Even if this was a game programmed in flash..you can't keep the mouse inside a flash video..at least you shouldn't ;)
Nevertheless, I'm amazed that such a great 3d game runs smoothly as a flashgame..even if it's 14 years old..guess I should refresh my outdated flash skills :)
Really like the style, but why is it called 3D? And the criticism about the keys is justified, I lost some points because I was in a rush and misclicked.. :)
But nevertheless, nice Sudoku game.
