Cannot finish Beelzeblock challenge

[MasterLuigi452]

Hello. I enjoy this game greatly.
However as soon as the background shatters and changes, the game slows down dramatically.
It's just like old Transdimentional Leakage back in Super House of Dead Ninjas.
In addition for transitioning to final phase, the Beelzeblock keeps hanging around at top of the map. Not falling down to ground level for me to finish it off.
Any solution to this?
Thanks!

iirc... I believe you have to jump on the fists and then proceed to pew pew him in the face, barring bad memory.

I've been looking for a solution for the game slowing down just now, and there doesn't seem to be anything on it :/. Shame, I was really enjoying this game too but these final levels are just unplayable now.

As for not being able to finish off the boss I never ran into that problem, have you tried this several times?

Same problem with Beelzeblock challenge. Game slowing down too much to be played. Fullscreen OFF helps a little but not enough
