Fun game! I'd like to see options matter more somehow... Maybe for a sequel. For example, I'd like to see occasions where you want to make fast tanks vs. big tanks. Maybe add alternate 'paths' for tanks with an amphibious wheel set or similar?
The tank moves very poorly, and the scale means you need to be right up on targets to hit them. Not terrible, but needs a lot of work. Also, the terrain image doesn't tile well at all.
