Excellent game!
The game had excellent user feedback because of the warning signs and sound effects, and I caught on pretty quickly for what I was supposed to do.
The changing music was very smart because I initially suspected the game to be an "endless runner" type game but realized that wasn't the case because of the escalating music. And boy am I glad I stuck with it because the tank boss fight was really fun and engaging!
The voice sound effects were a nice touch too.
The art was nice. The road, while plain, was going by so fast that it didn't matter. Only point of feedback I can give is to spice up the thumbnail, make it sell the game, because I probably wouldn't have even played this fun game if I hadn't checked it out from your comment!
Overall, excellent work though.
