I liked a lot about this game. It was easy to get into, very fun, had a unique and refreshing look and very cool gameplay. Great job.
My one critique that made me stop playing eventually was a lack of golden path. Not that it had to be linear, but because everything is hook-able, I had no idea where to go to collect anything or how to accomplish my objective. I like that everything is hook-able (it saved my butt a lot and made for great fast-paced momentum) but consider maybe a different color for objects that are targets or goals for the player.
And a minor point, I thought the momentum from a slash attack was too powerful. It was hard to predict and carried me over the edge almost every time.
Otherwise, awesome game. I really enjoyed it. Congrats.
