I've been working all day adding an awesome new feature to the level editor. It is now possible to turn any tile into a non-collision backdrop tile that automatically alters the semi-transparency to make it look like an awesome background item.
Look at the results!
Boring old background
New awesome background
I am now allowed to change the project progress from 40% to 41%
Thanks man.
I also like that with this new feature the user can make more interesting and varying environments- Instead of just choosing a set of finished backdrops.
