This is me getting 8380 points on the "One, Two, Kaboom!" level in the original Wonderland game.
Doing the start as fast as you can is convenient and idiot-proof, but not really necessary. The Kaboom! at the end requires you to wait.
When I enter the red teleporter, I move one tile left and two tiles up. That traps the Kaboom! at the top right corner of that small room. It happens before the screen catches up with the action, so that's why it may look confusing.
Anyway, enjoy the last level of World 2. Stay tuned, folks!
