Yeah I get it; it's a fun game. I loved the "COD4" style health bar, which makes it harder for you to see the more damage you take. Also thought the concept was okay.
My problem is that this game is completely dependant on luck. A skilled player could have to play through the first level 20 times; a completely novice could breeze through. It's not fair that I lose because of luck all the time, there was barely any skill to it. If I happened to avoid a bird/meteor and went the 'wrong' way, I'd be dead. You need a mini-map, a longer time to react, or more responsive controls - How can I move out the way of the obstacle I've just seen if the controls won't allow it? It's unfair, and causes massive frustration.
I'd recommend resubmitting this with some better gameplay, because this could be really good. Consider some bonuses and 'extras' too.
