Not very original.
More or less a carbon copy of the WIIPLAY tank game.
With more irritating sounds. (the Trumpet!! Oh my god this thing is so annoying!)
With repetitive maps
With dumbed down gameplay; the tank is SO slow. One can pretty crawl around faster than that tank.
..you can only get an upgrade every 5 level, wich is only a minor mod each time.
Why not make us start with an upgrade choice staight away?
No extra lives as reward for beating levels.. it count as an upgrade. So its useless; why waste a precious upgrade point on a life? That choice is nothing but a lose-lose situation, unless you already topped your techs.
Controls are about the tank's current facing, so its quite confusing. That and the slowness of it make the game quite punishing to play at first.
Sure your game works. But you could have done it better and more original.
