nice idea, but need to balance it better. Simply doubling the price of upgrading and doubling the creep hp doesn't cut it when you've got the three armour types. Maybe make a more expensive tower that's effective against all armour types. 3/5
Ok..needs improvement. Unlimited ammo for the main gun, more time would be good and a shop to buy weapons? With the last bit, that might be included already, but I never got to one.
Ok.. definitely way too easy. 2nd go got to Field Marshal and when I got to 2mill points and had everything upgrade fully apart from missle regen, I got bored. The lag was bad as soon as I hit full laser spread too.
It made me sick with the entire map turning a seconds slower then the car turning. Make one of them static. Also stupid that in the career you start of with 'medium' difficulty races and have to unlock easy.
