As others mentioned, the easy difficulty is very difficult when you first start learning how to play. Ships come in too fast in too large numbers and it gets hard to shoot them down without being overwhelmed. Other than that, it was a very good game. If that was easy, I am not looking forward to playing the hard setting. 4/5
Also, as others mentioned, there is a formatting issue and it does not fully fit on my screen. It appears that it is only on a laptop screen, but I could be wrong.
It is all about timing, guys. Get the timing to get the moves in. I am impressed with the combat system. For how it is set up, it shows a fair sign of complexity that as really worked out in a simple way. Great job.
Ally AI is brain dead stupid. You tell them to attack someone and instead they get in a line and attack one at a time. Also, building a wall is so slow and it is such a pain. It is a great game, but those things ruin it.
