I missed singleplayer games about tanks and seeing one in your sick as hell style is amazing! The game feel is nice, I like the consistency of damage, which let's me know that third shot is for sure the final one. It is interesting to figure out how to deal damage and dodge incoming shells at the same time and the environmental aspect of buildings that can be destroyed, but cover the map with smoke - is a nice addition to the whole thing.
The gameplay and content even though quite simple, doesn't really get stale and has quite a bit of potential.
The UI and whole perspective of looking out from the tank's window is a cool idea and just experiencing a tank game from first-person this way is an experience I didn't know I needed.
