It's fun, but it's not great.
Pool on unusual shaped tables. There's only one variant (a slightly modified 8-ball game), but about a dozen or so tables. The physics are usually OK, but there are time when it goes a bit wonky and the target ball behaves as though you'd hit it on the other side or it claims you hit a ball that wasn't on your path.
You're limited to a top down 2D view. The power available is a bit excessive (IMHO), but that means that it's hard to play with much finesse - you try for a fairly gentle shot and the balls go twice round the table.
The AI is extremely variable, sometimes managing inhumanly fine cuts, sometimes missing all the balls entirely or more often than you'd believe just shooting the cue ball straight into a pocket.
I've only played vs the AI, so I don't know what online PvP is like - assuming that the physics glitches are still present there (I can't imagine they aren't), this could get extremely frustrating if you were trying for a serious game. Given that the whole point is the silly tables, you probably wouldn't try for a serious game, but that's not really an excuse.
For a few minutes fun every now and then, it's fine. I've had my money's worth out of it, so I'm recommending with these warnings. Don't expect a very realistic game, don't get frustrated with the glitches and just enjoy the idea of playing on a heart shaped table. And probably don't play against humans unless you all know what the game's like.
