Unfortunately I felt I had to knock points off for the use of Zelda 2 and Megaman sprites. The game seems like it had some sound ideas but was lacking on some key elements for me. Sound would have gone a long ways towards making the disappearing blocks work better, and overall the hit feedback in both directions could have been improved. In addition the switching between mouse controls and keyboard controls felt awkward.
As for the bosses, I actually don't know what emerald knight did for his attacks because I was able to just stand in his hitbox and dps-race him.
It's a good start, but does need some polish.
