Actually a good game.
I hate avoiders most of the time but this is decent. Needs tactics because of the medal bug (you can't just double your points over the point what the medal required).
The graphics needs some improvement (:D), and the crash should be fixed, but actually I would play this again if somebody were remake it.
What I really missed is a good guide eg.:
There are 4 Pathfinders, they are green. They always following you. They shoot little red balls which can only travel in a straight line. There are only 2 kinds of bonuses: One will delete all red dots the other will double your score. Be smart because you need to have the exact amount of points for getting the medal. (I did like this bug. This should be a feature.)
So all in all: Could use some improvement (More songs, betterr GFX) but the game is decent.
