The drag mechanism is a little glitchy, and so is the fall effect, but otherwise a decent game.
The One Move on the 2 color board might need a limit, though. I'm up to around 6600x250x10! and it has no signs of stopping. Generally 50-95% of the field is matched every turn. This is only the 2nd time I've played this board. The first time I only got 6 loops. Lol.
And trying to exit the level while it's endlessly looping doesn't seem to work.
