I had a ton of fun playing the campaign mode on the easy difficulty. The buildup of challenges was great, the pace didn't feel too fast (which was good), and I liked the story as it unfolded.
The variety of enemies was good too -- the small drone things that fire quickly are a pain! And the mine with swirly attacks is nicely balanced with slow movement.
In terms of the story (no idea if this ends up being the case), it would be pretty cool if the AI guiding the player ends up being evil, and the enemies were actually the guards of the facility doing their job. I also really liked the the antagonist was a woman :) Yay for representation!
Keep up the great work!
