Groove heaven is simpler than simple. There are two buttons on the touch screen, Move and Turn. These need to be tapped in time to the music to complete a simple platform game.
The story is that a Devil Lord has fallen in love with an angel from the "wicked land of Heaven". He charges a devil girl, Rhymi, whom you are in charge of, to take to the angel a single Rose, the eternal symbol of Love. Along the way you will encounter Cats, Dogs and Frogs, which all bar your way.
The meat of the game is going up the Tower of Heaven in Arcade Mode. There are 30 levels in this mode with 3 Roses to collect in each. While the Roses do add to the re-playability of the game, they do not alter the ending or give you any other perks. There are also musical notes to be collected within the stages, collect 6 of these and you get an extra life.
The graphics in Groove Heaven are beautiful, but with 3 different environments encountered throughout the Tower. It has a very unique visual style that suits the equally cool music. If you tap out of time, then Rhymi will "stumble" and stop for a moment, which has very little effect unless you are at a critical moment.
The level layouts are incredibly linear and you will have no trouble knowing where to go, which brings me onto my next point. Groove Heaven is incredibly easy and therefore, short. Even collecting all the Roses and replaying Arcade Mode to death, you shouldnt be spending more than 3 hours on this mode. While I have mentioned that it is easy, there can be random difficulty spikes which are frustrating, but if you have enough lives (which you will) it is quite easy to get past them.
There is one other mode, Timed Mode, which has a good stab at extending longetivity, but is just a reskinned version of Arcade Mode, which you play in one go through. Considering this is a £5 title, there is not as much on offer as would be expected. That said, while it lasts, it is and incredibly enjoyable yet simple adventure.
Overall, this is a nice game which is a lovely time waster, but it is critically short
