Great game! The voice acting was very well done, and the graphics were nice too! The impact of a missile hitting an enemy tank also felt really satisfying, contributing nicely to the "juice" of the game.
The controls for aiming felt alright, though I feel like it could have been a little easier to use. Additionally I did run into an error where I couldn't be killed by tanks, the hp getting into the negatives (the error I'm getting is that the FadeToBlackDeath animation was not found, at line 1128 of scene/animation/animation_player.cpp).
Other than those two problems though I thought this was a well made game. It was fun, and the tutorial and intro was nicely informative and well put together. Well done!
