The design of the bosses is pretty good, cool concept and that intro with the comic style is awesome!! I love the multiple phases, did I already say that the bosses look amazing? The art and animation are good and I just can't believe how good the boss design is. The only thing is that I spent a lot of time figuring out how to use the controls and how to play specially that spinning attack took me a while to understand how to use. Overall it's pretty good, good artstyle, good job!
