Explorer game, 2010s

[rave_exe]

There was a game that you shoot zombies and other creatures. You were square head and you dont have body at all and enemies were square too. Not like pointed squares it was more like curved squares. You shoot them wave by wave. In some waves you have to deal with some bosses. One of them was black and had pointed teeth. You can buy guns at the shop on the map from a kind of cart and seller was waiting for you out of the cart and he had long black hat as far as I remember. This game was like "boxhead" which is also an explorer game. You can see your character and monsters from above, just like in moba games.
