Here's my review after playing the campaign
Positive:
+ A really nice story!
+ Good gameplay
+ Pretty ok cinematics, far from worst I have seen!
+ I lieked the Brakak model
+ I couldn't see any spelling mistakes, that made my day (*is a person that hates a lot of spelling mistakes in cinematics

*)
Negative:
- There's no picture at the campaign screen, where you choose that you wanna play first map or interlude.
- There's no body in the bed at the "dream" cinematic. Wouldn't it be possibly to just add Brakak with death animation in bed?
- The ground, rock thingy, under the Dwarf General at the training ground bugs.
- Brakak got the icon of a mountaineer when selecting several units.
- I believe it was a little strange after he killed the spiders we got to see the tanks, then poof, and he was back at the house with 4 other people. You should add another cinematic between those two.
- At the ending cinematic, the flag on the right bugs. Was just a bit irritating when he got invisisble sometimes.
Overall:
Overall your campaign looks like a very promising project! Too bad you havn't got any further on it, can't wait for the next parts!
