Sorry for the long time I took.
I just could finish my claimed level Shell heaven.
Here is another screenshot of it:
Here is the download link (also availiable in it's own topic):

I had some little troubles here and there, but now everything should be fine.
I first liked to change up the colors of the trees too, but due to the insufficient amount of suitable 1x2 BGOs, I just scrapped that.
Also, I am not too sure about the red color switch in the shadow world. Please tell me if you think that it should be removed.
Also, every feedback to anything else about the level is appreciated too. :-)
P.S: Here is a little sprite sheet with the requested SMB3-styled eyecandy-grass:

This is how it looks now in the level Desert maze:
I also updated all my previous levels and their downloads.
I removed all the mentioned bugs and also updated their names to the more appropriate forms ("01-07 Dungeon Of Pain" instead of just "Dungeon Of Pain").
Also, I fixed the start events in every level, which automatcally pressed the run-button. Now only the up-button is pressed.
EDIT: I like to claim the level "S-1 White Savage Zone" next.
