Basic and poor.
Indeed, really boring.
But you put zombies, that's original and unseen !!

Er...
You should better and with OTHER monsters than zombies. It's just too common

Boooriiiiing....

A very basic one button shooter. With only one weapon, one type of zombie attack, and not even a scorecounter, this gets repetitive pretty quickly. And the fact that if you just go off screen, the zombies won't touch, and you can just wait 'm out doesn't help either. The endbosses you can take down by just standing in one place, and they will never adjust their fire.Every boss is the same as the last one when it comes to attacktrajectory, only a bigger lifebar, thus making the boss mode a bit redundent. Also try to make it so that the screen pushes you forward, instead of swallowing you into immortal limbo.A way to get back to the menuscreen, when you have picked a mode would be handy as well. It's gonna take some elbowgrease to fix all of these issues. But once implemented, it will hold peoples attention a lot longer.
