I really like the general idea - it feels very epic. There's some really big problems that hamper the fun, though: it's too hard to tell what's going on and I usually have no idea why I died. The character keeps moving a good amount of time after you let go of the movement keys, which is especially troublesome because you need all the precision you can get when one-shot can kill you. And although you can shoot the incoming barrel-bullets to destroy them, the mines that quickly litter the battlefield can't be destroyed by any means I found - so the game becomes nearly impossible the longer it goes.
