I was stoked to see this game in the app world when it was version 2.0, downloaded it right away, only to find out the controls were very unresponsive and made it basically unplayable. Fortunately, it has just recently been updated to version 3.0 and works great! Not sure if anyone is familiar with this game but it's a retro tank game that many of you might recognize. Figured I would share it since, in my opinion, it is one of the hidden gems in the Playbook app world.
Attached a screenshot just in case you don't recognize the game by its name (I didn't until I saw a screenshot).
