The first time I played, the game froze on 3rd level. Several playthroughs later, it happened again on the fourth. So it would seem that there are still some bugs to be ironed out. Other than that, there isn't much to say, really. Fairly standard match-3 gameplay. Your last level determining how much time you have for the next one is a nice idea, but in execution I feel like the time limit is a bit too short and the playing field a bit too small.
