Pretty sure this is my most played DS game. As it turns out, crossing space invaders with bingo and rhythmatizing your shots to a crazy ost is an excellent idea. Oh, and there's Darius style branching level selection.
An interesting take on Space Invaders, with some funky visuals and gameplay adaptive music, this game is fun for an afternoon, albeit the gameplay gets a bit stale after a while. First stage OST is a banger, highly recommend giving it a listen.
My favorite Space Invaders ever. The flashy colors, trippy backgrounds, and fast-paced shooting, of course - it's just a blast to play, not to mention incredibly addicting. Pick it up, goes for super-cheap these days! (got mine used @ EB for 5.99)
I'm Sorry but I have too much fun with both games. The visuals, music, and gameplay are just amazing. they really went all out on both games. I highly recommend it for shoot-em-up fans and people new to the genre.
