Wow, this was amazingly polished! looked very good had that humph in impact and subtle animation that really gave it life. Gameplay was fun, reminds me of geometry wars. variety took a while before showing up, but was cool. Ship control, was thight. core control... troublesome. I'm sure that was the intent but since its your lifeline, its a bit unfortunate that it is so unrully. because that gets you killed. -.-' (To be fair, dragging the core to health is how the action gets going)
Very nice all around!
