My first run ended at about 2430.
I dig the concept here a lot - the visuals remind me of games like oldschool Asteroids but the pacing feels like it's going to hit something more in the neighborhood of Geometry Wars as difficulty ramps up.
Do you plan on adding any other modes to the game? I was sort of expecting the missiles to go flying off the edge and come in again on the opposite side instead of ricocheting and feel like a "borderless" mode might shake things up a lot.
( If enemies that appear at harder difficulties already do this, then I guess I just need to get good :P )
