Art is amazing! I especially liked the art of enemy tanks, they look so good! Generally, I loved the artstyle.
I think you should have put controls on the game. Or at least in the description, because I couldn't figure out how to fire. Also, the idea of driving to the enemy tanks in order to engage in combat with them is kinda weird. I thought they were an actual enemy tanks that you had to shoot.
As a fan of tank games, I love the concept of manually controlling a tank.
