Didn't see a thread about it.
Continuing the DS being the best current system:
This is an interesting take on the shmup. Everything is stylus controlled, which I thought would be a pain in the ass, but works just fine. You play as a triangle that shoots fireworks at various weird things in the sky by flicking your stylus across the screen (like lighting a match) at different angles. If you miss your target then the shot explodes and you have to dodge your shrapnel - along with any regular enemy shots. It's really fun, and bargain priced at $20.
You'd be wise to pick it up.
