This game suffers in relation to Solitare Til Dawn. Its interface does not follow Apple Interface guidelines. It does not allow some legal moves. And the trial restrictions are such that no one can complete a single game. The basic 3D interface is fine, but the animations seem to be a little over the top, if you are going to be playing for more than 10 min.
This game does have promise, if the developer would actually take the user's suggestions to heart and make the changes. I sense the developer really wants to improve the game, unfortunately, so far the change log indicates too little to improve the mac user experience.
This game could be so much better without that much more work, and I encourge the developer to do so, because he is leaving money on the table as it is now.
