Very fun and polished:) Loved the visual theme of the game.
With a more simplistic visuals you managed to add lots of great polishing. I loved the detailed rock shapes and the effects feedbacks on combat. Overall it was a very well-constructed game. In addition, the movement system felt interestingly realistic for a tank. giving a fair degree of difficulty creatively added.
As for customizations, there wasn't much of a focus to it. Although it is a bit of a hindsight, changing the tank's colour or shape could benefit. However, with the current customizations, many great mechanics were added!
Great job!
