Hey mate, this game has potential, but seems a little bit unfinished yet. Aiming is just a pain in the a$$, sorry for being this harsh, but seeing cash-cow after cash-cow slipping away while shooting smallest and farest threats, its just rubbish. Money is the key, and my turrets dont shoot the key... Balancing is not perfect, too. But overall, it has potential, but the shortcomings should be fixed.
Woooow, really hard... Nice game, but perhaps the luck-factor in the beginning (finding proper weapons / items) is a little unbalanced. But highly addicting!
