I added sounds and the thing that shows up when you beat him YIPPEE like if you want the next boss (this guy a toughy) he goes round 2 times after he is hit (note at the end when he at 0 you have to jump over him until he stops)
for some reason the remover I used removed some of the spikes on the sprites because they were from yt thumbnails so the grey he was on blended with the spikes
