This game is incredibly unrated. Of course it has its flaws. For example, it was a bit annoying trying to read the moving text since characters were constantly moving around. But the script, the atmospheric music, not to mention the innovative and symbolic gameplay is simply amazing. Deserves at least a 4.5 in my book.
First off, this game is amazing (especially the art style and music). But the combo system does have a pretty major flaw; Your S combos are WAY too unreliable and often miss near the end. Since S is your only hack n' slash alternative to A, it ends up being a pretty big set-back (ended up being forced to spam A during the Hard boss). That reminds me, during the Hard boss your character should be able to fly back up after falling. Thought it was a bit weird since he was able do it during the Easy boss fight. Maybe add a big health penalty to retain that pressure of avoiding the edges. Overall, it was still a great game. 4/5
