Really great game. One of my most played dual stick shooters on my iphone - I liked it so much I bought it for my Ps3 (though haven't really played it much on there though). I always play it on the hardest setting (Suicidal), some songs are so intense. Some of my musical purchases were based on what I thought might be great songs/albums to play. The Boss Rush mode is pretty cool too. Best Survival time (according to Gamecenter - had to restore my phone so had to restart the ingame stats, which only lists 21:18): 26:59 According to the game on my current phone for Boss Rush Mode: Wave 35.
