Whoo! ^_^
Already gave it praise on other sites weeks ago (I think), but anyway, I'll just say this: Great job. Same addictive concept with more piled on, as well as incredibly fun levels. You can do a lot with the new additions! I'd suggest what others suggested on the forums. Spikes, tokens, keys that unlock doors/the exit portal, one way walls, etc. 5/5, 10/10, favorite.
For the people who visited Boombotworld: I'm csd there. I'm one of the top builders, so I'll be easy to spot. Try "Options 2", "The Trouble with Time", or "Intense Electricity". :) (Also, a few of my recent levels mock the top levels... don't think much of it.)
