great game
i liked it a ton, i played through like 5 times, got all the weapons fully upgraded and got every achievement except shotgun frenzy, and i have no idea how to get it, the graphics weren't all that great but it didn't take away from the game-play, it could have had some animations somewhere at least, like walking legs and such, and holding the shotgun right instead of like a pistol would be good, customizability would be another awesome addition, i found one glitch, after you beat the end boss, if you push pause the credits will scroll over your pause
and then you get stuck there kind of the game continues you can shoot but you can't get back out of pause, and you can stack another pause on top of that for a real pause, however if you unpause you just get back to the original one while the cows kill you
