I've had the experience of playing that awful game. It's a shame, since it was made by the same people who made RPG Maker 3 and Fighter Maker 2.I bought Whack-A-Friend a few years ago, thinking that it would be a nice novelty app like Photo Dojo. It was only $1.99 USD, so I decided to give it a shot.
What I got, however, was a game with annoying, bland, and generic music and gameplay, and only had one gameplay mode where it progressively got harder and ended when you missed too many times.
Actually I bought it and give my 3ds to my sis so she gets me some items free and sometimes rare pokemons. Not that bad....Dream radar. Screw that dlc garbage and screw gen 5.
