Its a Start

The tank looks pretty good though simple. The landscape doesnt. The staircases are large enough that the tank should be able to drive up them. The so-called forests are a handful of trees. The tank physics are pretty awful as it doesnt look at all realistic in the way it takes bumps, let alone when it runs into a really steep cliff. No scoring. One read-out. One weapon in the free version. Two types of enemies; one mobile, one not. Explosions and flashes completely obscure targets and theres no targeting system of any kind. No physics used for your weapon or the enemy. Fire travels in a straight line except when it bounces off cliffs which causes it to ricochet off on some other straight path. Sound is monotonous and simple. At the beginning there seems to be a voice saying something but its very very quiet. The "Diary" is extremely mundane and poorly translated into english.
On the whole, it looks like the very early stages of development of a mediocre game. Another years work and maybe it could be something.
