I finally played it! Good game. Didn't play against anyone. Just trundled around a bit.
Tank sounded really good. Music was cool too. Nice presentation. Plenty of options. Water looks really great. How did you do that? Gameplay is more of less solid.
Criticisms/ suggestions
I got stuck in the volcano for a bit.
Dark levels too dark for me (although i'm playing in daylight at the moment).
When i selected 1 minute round, it went straight to the end of game stats on loading.
Couldn't uncheck "friendly fire"
when clicking on menu options (not the drop down button to the right), got a flash of dropdown menu.
No mouse control of turret when in exterior camera view.
Sometimes hard to tell tank orientation relative to turret unless you look down at your wheels. Maybe something on the HUD could show this.
Tank driving felt very "slidy"- if you don't accelerate or brake and just turn, you keep sliding for ages!
Looking at your media, it looks like you had a radar "sweep" image. Wasn't showing up in game. Not sure if you haven't put it in yet, or i have a shader problem. Would be useful to have a video to compare with.
Radar texture mapping effected by filtering from one side of the texture to the other. You could try set object texture flags, or put a bit of a clear border around the texture.
Edge of world is obvious.
It's good though. I look forward to further developments.
