This is the proof that there's no need to do complex art to make a visually appealing game !
The customisation of the tank works pretty well, even though it lacked a bit of strategy imo, I just put all the guns at the center with the wheels and put defense around it, and it seemed to work pretty well.
The shooting is a bit harder than necessary, mostly because the projectiles are very slow. I wish the velocity difference between weapons was a bit more noticable, I think it could add a lot of variety without needing more work.
Aside from that, the gameplay is quite enjoyable, it's too bad there is no sounds to make combat even more epic !
