Thor has released the sources to his game Gears Of Fate.
The goal of “Gears Of Fate” is to reach the red square with the green ball. This is reached by rotating the board, while undo is possible while the board still rotates.
Colored tiles are removed when three of them are regrouped. Grey tiles can not be removed at all. Dark colored tiles are removed once all tiles of the same color have disappeared.
Thanks to Thor himself for the news via e-mail!
