Level 89: BLOCK BUSTER (VCZO)

Richard Field: Go to the high right red button, make two blocks (one at a time, stepping on them) and get the red key. To do this from the starting point, go: URRDRRRUUDDRUU and repeat. After you get the red key push the left block up two spaces—quickly—then, very quickly, go LRD. Push the block you made into the water, go step on it, and repeat until you have made the path to the green key. Now, from the bottom, open the green doors and pick up the chip, go up and open the red door and pick up the chip. Now, quickly go down to the bottom of the four blocks area. Slide up, watching out for the moving blocks, then down, watching out for the moving blocks. Make sure you don't push a block when you slide. Now travel up and left and repeat the sliding/avoiding pattern. Watch for the pattern in the blocks movements and for the pause. Take your time. At the last block sliding area, circle up and right and push the top sliding block into the water. Get the last chip and exit.
Marie Setliff: After you get the green key and pass through the first ice block thing to pick up the first chip, I find it much easier to get through the second by simply closing your eyes and running for it. I have yet to block myself in doing that.
Ben Friedrich: In the ice-area, touch the block in the bottom-row from below, that will stop it and you have only 3 blocks to beat.
