I've finished most of the artwork for the third "world", the egyptian Underworld, and I've also been working on new levels. Click here for a vid of a new level in the Underworld.
Right now I have 13 levels, I want at least 30. Making a level is fast once I get an idea, the problem is getting it. :)
Is there any particular reason hitting the green boxes when you aren't green creates more of them? I don't recall seeing that in your other videos - and it appears that the level would work fine without that feature.
