One of the best puzzle games ever released on windows. Perfect to chill out and relax after a long day at work. I really missed it and hope it will be back in some form :)
This is one of most creative puzzle games that have existed 'till nowadays. This game was created and developed by the creator of Tetris, Alexey Pajitnov, and I'm waiting for a great remaster for this game.
I think this is owned by Micros*ft so chance of this appearing here are almost nonexistent. Still this is one of the best puzzle game on PC from that era and I would love to play it again. Very good audio visuals too.
