I agree with SensitiveJerk
I didnt mind the music though.
What really bugged me is:
Getting blinded by goo that my feet touched and not my eyes. Ok so maybe it emitted some kind of blinding gas. Anyway the blinding length is way too long and annoying, even as a deterrent. Items that get dropped by the enemies with black goo should be dropped on top of the black goo, not under it (to show them better to the player).
The Golems that explode and throw harmful chunks everywhere are ridiculous.
Why would those rocks keep flying at a constant speed like that. You'd think gravity would pull them down to the ground and stop them.
The descriptions for the Personal skill/speed/armor upgrades are buggy. When i got full skill it said i could keep adding to it for speed? Yet there was another description for speed itself.
Also i see no incentive to put points into upgrading bows early on. It seems pointless because you'll eventually get better weapons. This is not the same thing as using gold on early weapons mind you.
Fun game though, i finished the campaign.
