I picked this up last night for $30... Generally I don't like buying a game without seeing prior reviews, but there isn't much info out there on it, and I figured $30 was a fair risk.
Well, so far I am not impressed. While it does include solid gameplay physics, it's obviously a low-budget production with a clunky interface, annoying menu, and questionable AI with no difficulty setting.
I may give it another go, but here are some annoying things I've found so far:
Menu is cumbersome - have to scroll to bottom of long list to start game, and it takes several seconds
Can't figure out how to change view before shooting
Two player game (with 2 humans) requires 2nd Wiimote
No difficulty setting for CPU player
So far, playing against CPU at 9 ball seems pointless. It made the 9 ball on the first shot each time (carom, combo, etc). Reminded me of playing Dead-Eye Dan in Virtual Pool for the PC
Unimpressive "prizes" for winning (a "blue" pool cue? yippee)
I have yet to read the manual, so I may be missing some features, but for now I wish I hadn't bought it. It definitely makes me appreciate the work that goes into a polished product like Metroid Prime 3.
