Surprising
Damn damn damn damn! This could be a sick, killer game but there are so many problems you have to iron out.
FIRST AND FOREMOST, have that dude wield an axe better, he looks so casual and jaunty just strolling through the blasted hellscape of his mind. Make him bad ass and increase the range on the swing animation, I have no idea the arc starts and ends. The enemies have flavour and style but the protagonist is melba toast bland.
SECOND, add more flavour, backgrounds, foreground textures, varied platforms. This is his subconscious, so the levels should not look so 'Game & Watch'.
THIRD, hit detection. The boss nailed me with three direct eyebeam hits and only one of them registered where as I snuck up on one of those hell seals and died instantly from six feet away. (Why am I transported to the beginning of the level?)
With polish, this could be good. The narrative is suspensful and intriguing, but I hadn't the desire to play very far because of the MAJOR flaws evident.
Put some elbow grease into this sucker and you've got yourself a winner. I really want to see this refined because the fundamentals are there, it just needs tuning.
Great start, follow through.
