I played it for about 15min. It's an awesome little game and i really liked the feel of the tank. The visuals have real potential and make for an awesome atmosphere. And the models are awesome too.
With a little more mechanics like upgrades (i was thinking night vision and a like flashlights to blind people with night vision or something like this) and multiplayer ( mainly LAN would be really cool) and instead of driving through environment that this gets destroyed this could be a super cool thing to play with friends after a long day of university.
I hope you continue working on this gem. Good Job!!!
EDIT: I played on linux and it works with no issues.
