Did you try uploading time trials or did you give up because online play didn't work? My device won't play online matches but will still upload and download time trials, so you may just have the same problem.

I've found that you can keep the resistance effect from level 8 and use it to jump straight to the floor in dracula's bedroom, but do you think, jumping down to the checkpoint below spawn and quickly hitting the button, would be a viable faster strat? finding a setup would be a bit tricky.

It would take some very unlikely mob AI, for the creeper to explode without killing you before you pick up the diamond, i think. But it's probably technically possible. I like your way of thinking :)

Do i have to play using the specified graphic settings?
