I received this game free as part of being the 3DS Ambassador that I was. I will make this short. It is a game, where you do things. Honestly, I haven't played this game all that much. It is fun but very simple. You are a balloon fighter but have to pop other fighter's balloons.
It's a fun way to spend some time but it is definitely an old game. It hasn't aged well either. As arcade type games go, it is pretty good. If you don't feel the need to play this game, the only other game I can think of that is like this game is Joust. Both are great games.
