I really don't know why anybody would upgrade attack skills, it seems really dumb. Every planet's def is conveniently just as high as an attack upgrade, so i don't know what an extra 2000 or something attack would do for you
The skill "Freeze defend" is so stupid. Trying to kill the powerful ice mage is almost impossible because as soon as he stops me from doing anything he screws me in one turn... balancing please?
So i clicked the soul thing that i got from killing the demon boss caues i didnt know what it did, so it whisked me away to this soul world and the insanely hard boss killed me in a few secs... thanks game 15 MINS OF PROGRESS GONE
I didnt really have any problems with the game difficulty, farming gold is super easy and maxed out laser deals with lots of things until you get both turrets, then you can just spam rockets to create an impenetrable defense line
The controls are awful, mainly because you need to use the numpad to move. If you resort to the arrow keys you can't move through diagonals and its really annoying to switch hands, also Q and W are too close together, Q and E would be just fine. This is an old game, but yeah, the controls aren't great

Yup, I might have to do an unlocking feature where you can't purchase an expensive recruit until you unlock some of the lower recruits first...
