I speedrun your game :)
I think I might be letting my competitiveness show, but how's this? I also managed to complete it with 107 seconds remaining once but didn't generate enough mana to pass the ritual. Very fun game to play, had a great time rolling around gathering bones and becoming more and more unwieldy as I increased in size. Very impressed how you managed to get the Katamari mechanics working, and though I had some difficulty sometimes getting the bones to actually stick, the ground slam helped a lot with this and mobility. Could definitely see myself losing a few hours to this game if it was expanded with more levels.
