So I think I've learnt just enough about GameMaker to start putting together a proper 'game', or at least enough for my needs, thanks for all the help guys!
I do have a couple of problems someone may be able to help with though.
Firstly, in the example video below you can see that the fade-in from black doesn't apply to backgrounds set as a foreground--any way around that? or should I create what I intend to be foregrounds as objects and place them at a depth above everything else?
(The fade effect is just a draw event of a rectangle with transitioning alpha based on room speed, currently set to -100 depth)
Secondly, any other animation files GameMaker can read apart from GIF? I know of a tedious work around or two to avoid getting the white outlines/pixel specs on a GIF with translucency/soft edges, but it'd be great if it could read some other format which allow animations which aren't clean and solid (a photoshop or AE file of some sort?)
Example video here with the foreground and black plant which grows with the white speccy outlines:

Excuse the crude drawings/sounds, simply put together to test out the GameMaker functions and such~
