Stuff is way to expensive
The concept and graphics are cool, but dude I could login into steam to buy an AAA game for the same price as the VIP pack. Also you can only unlock 5/10 levels of engine and tank without the VIP pack? This is going to become a p2w garbage game. I suggest for you to make 10/10 engine and tank levels free, add more perks to the VIP pack, and reduce VIP pack price by a lot.
