The moment you see your screen absolutely full of enemies, your heart begins to race, and the game sets itself up for grand battles galore. The main issue is, this feeling is short lived, and it doesn't take long for the battles to turn into a chore.
A basic overview of what the game entails is as follows:
Move a bit
Get to battle - press the same button a lot
Move some more
The enemies types make no real difference at all, especially as, at time, there are so many on screen, you just cannot make out what they are. At no point does this game provide anything else but thoughtless button mashing.
The amount of onscreen activity can sometimes cause the game engine some issues, creating quite a bit of slowdown, making the game a lot less responsive as you play.
From a technical standpoint, the game is attractive, and the amount of onscreen action is impressive. However, playing it just becomes a tedious mess which you lose patience with fast.
