Loved the goofy little images of the tank reading a book and such, very charming.
Maybe it doesn't suit the gameplay you're aiming for as its meant to be arcade-y, but I feel like the tank needs more weight with its acceleration and stopping - even subtly, it should take longer to accelerate and slow down since you really do stop on a dime. Perhaps if you have a friction setting you could turn it down so it kind of slides when you ease off the gas... maybe tank drifting, even? I kind of wish you could also sort of slam into enemy tanks to damage them, though that's maybe unnecessary.
Sound design was solid, guns are nice and punchy. Some additional ambience like wind rushing past the player when they're at top speed would be neat, maybe even add a sound emitter to the enemy shells so they make a whizzing noise when they fly past the player's tank? (Something like this)
The destroyable walls and chunks of spaced armor flying off the tanks were a lot of fun, very good detail in the enemy tank destruction.
Also appreciate that you added a mouse sensitivity option this build, much better!
