Fun game, but there is balance issue.
1) Early game gets incredibly easy once you get a single sniper, they can pretty much one shot everything with the ammo box buff, they are OP as hell.
2) If you spam snipers and mortars + buffs + tanks covering the rear, the late game is a joke. I didn't have to use the shocker, flamer, and the rocket-launcher at any point during the game.
The pathfinding is flawed, your unit would stop completely if there is an obstacle in their way.
