It's definitely cool and interesting... sorta limited in its usefulness, though. Also, there's two things that weren't clear to me: 1) how do you create clouds? and 2) what's up with the phrase "control the mouse pressure" in the tutorial? I don't know what mouse you're using, but mine really only is either clicked or not clicked... there's no "in between," so to speak. Anyway, pretty cool stuff.
1, The mouse keys activate the Paint brushes : You move the mouse to paint.
Right mouse click (hold down) Dark green blocks
Middle mouse click (hold down) Clouds
Left mouse click (hold down) Grass and vines.
2, "control the mouse pressure" Bad description, I meant you can create different effects depending on how long you hold each of the buttons down...it takes a bit of getting used to.
I agree, at the moment it is limited but i will improve it (more brushes)
