Once there was an ugly bossfight, and it was so ugly that I really cannot give much of a shit about any positive qualities this level might have, and also everyone died. The end.

A classic from the 2.0 era that rewards the player for being patient learning it. Although the visuals don't have the most coherence, it's still very much competent and honestly compliments the frantic and varied gameplay throughout. Give it a chance and stick with it, the reward for making it all the way through vastly outweighs the time it takes to learn.
