Only played a few levels but I have the same complaints most reviewers probably had. Boring, simplistic gameplay. Shallow platformer elements. I have seen it described as a brawler too and it's even weaker in that genre. Graphics are pretty crappy too, even if it seems intentional with art design.
Was surprised given the amount of hype it had. I'm not swayed by hype though, but I did expect more from someone who has consistently achieved greatness like Cerny has.
Whats that in your sig ?
And if it sucks when it comes out, I'll say it does.
