I'm not sure if anybody else noticed but I can now finally find it on the market with my droid =) the game is free and is extremely addicting and fun to play. I'm running a rooted droid with jrummy's cyanremix v 18.104.22.168 and was able to see it, not sure if it makes a difference though.
Just thought i'd let everybody know that it is playable and findable via the droid now, its made by "glu" and has great graphics and gameplay is smooth. I recommend the game to everybody. Just search "bonsai" in the market and it'll show up
