WeZap for the pb is normally a paid app but it is currently free. It has decent reviews so far and the price is right
I just downloaded it but wanted to post this before trying it out.
I didn't even know this game was out there. It was a complete suprise to see a game like this work really well, and above all being free! It's polished and smooth. It's a multi-platform game wich suprised me a second time as i didn't held this game for a port.
Check my video out and you guys should definitly give it a try. I made the video to share with you guys how great this game is!
