Here's how I did it:
First I walked by a tower of colored blocks, pulled the top one off and used it to smash the rest of the tower. Then I wandered around and pressed a few glowing blocks that changed color. Then I found some more towers and walked through them to ghost-smash them. Then I found a magic cone that spawned blocks, and spawned a few hundred of those to see if the game would crash. It didn't crash so I went and found another cone and tried it again. Still no crash, so I started running and jumping through the piles of blocks I created like a dog jumping into leaf piles in the yard. Then I decided to start throwing things. First I found a big cube, and threw that. Then I found another tower of colored cubes, and started throwing those as high in the air as I could. The third one, a pink one, ended up flying wildly behind me over a wall, and another glowing wall appeared intersecting it at an angle. I walked to that glowing wall and solved the puzzle. Thank you.
