This game takes way too long.
Good concept, but there are many things I do not like.
1: You have to wait for all your vehicles to get destroyed before you can either reasearch another one or purchase another wave.
2: Each stage has way too many f-ing levels.
3: Lack of space for both your factories and your defensive structures.
I would like to see the difference of attack powers and the range of the defensive turrets, and I would also like the see the health differences on the vehicles as well.
That wraps it up for me.
Have a good day.
