Paper Airplane Chase is a great diversion that's easy to pick up and play but hard to put down.
Paper Airplane Chase is split into two main game modes: Endless and Time Trial. Endless is the mode that will consume most of your time, whereas Time Trial is just a fun and easy way to unlock moire courses for multiplayer. You can also go back and try to beat your fastest time, but you won't do that very often. The multiplayer mode is more of a side mode that's fun to play a few times if you have a friend over, but it's really not all that great.
I highly recommend Paper Airplane Chase, as it's one of the much better games out there on the Nintendo DSiWare service that's worth 200 points. For its price, it offers a great amount of value, and you will play it very often to try and bet your endless mode high score. My personal best 183, but I know that one of you guys has a score over 1000 already...
