4 / 5. Deep gameplay, but poor balancing. Spells are too weak for the mana they cost, and the skills page does not show the progress of light, medium armor etc. when you train those skills :-(
that awkward moment when you fight hard and are proud of flawless victory for 4 minutes for 4 missions, and then you think "wow my ship is all red bar and still no dead this cant be right"
Thanks for the bug. I have fixed it.
