Things that would vastly improve this already great game: 1) more units 2)more maps, including maps with "obstacles", similar to a TD where units dont just run straight but have to follow some path 3) RPG elements - a skilltree/upgrades would be nice 4) some sort of campaign to introduce the new maps, maybe even a bonus level to play as the aliens:)
Needs some tweaks and will be quite enjoyable. For example, it would be much better for the gun to be always aimed at the cursor and not lag to go there.
If you have problems with earlier levels (10, 14, etc), you should try to make long chains and cut them close to your cell, so all the units go to the enemy and take him over quickly. I do this to transfer units to forward cells and then fight the enemy, works great.
This is not a valid way of towing, you should use a hard line. Also, when using soft line, the towed driver has to do something very important, which he isn't.
