I bought Crystal Crisis.
It's OK so far.
However, the loading times are absolutely atrocious for a game that looks like this, and every damn tiny scene is a 15-30 second load in/out.
Also, I really don't like the board you play on bring tilted. This makes it too hard to line up what column you want when you are fighting depth perception.
The actual gameplay seems fun so far and has wrinkles in it that add more variety and strategy to things.
Overall, I'm slightly regretting this purchase. Perhaps more time will change my mind.
