Chamber 1, Level 8:
First, get on the left side of the block and push it to the right to cover the laser.
Now run to the other side and throw a seed up to the left of the block above you.
Run to the right so the clone pushes the block off the platform.
Retrieve your seed. Then jump onto the right block. Throw a seed up onto the block on the platform to your right and walk the clone over to the right of the block.
Walk left, using the left block for leverage until the clone pushes its block off the ledge onto the other one. Be careful here — I pushed the block too much and the laser killed my clone.
Jump over the block to the left and push it right to the other two blocks. Then use all three blocks as steps to get to the exit.
