Not bad but it is way too easy to exit the bubbles, which resets all living tanks in them. Accidental touches of the side shouldn't be enough to leave.
Needs a mute button. Nothing like having to start and then pause to get to a sound control. It's also nice after playing to find there is an autofire option.
I used to like this type of game but now I find it too restrictive at first and too complex later. There is very little different than many other build-upgrade rpgs.
I broke out IE 11 because Unity won't play on Chrome and still can't play the game. Too laggy and jumps around, especially when you get close to objects.
Buggy, laggy. first time I played, it stuck when the car stopped. second time, he got to the tree and the three controls are useless once he digs the hole.
