About the diferent outlines, you need understand that all is made by tiles, isometric cube tiles, etc..
I saw you said you didn't want to use outlines, I honestly can't think of any other way other than very clever shading, which I don't think is going to be possible as it looks like you're going with very simplistic tiles.
Yes but i also said, if this is the unique form to solve this problem i wil be use.
AndyT,
Why do you use cubes as blocks like that?
¿?sorry i not understand you ¿?
Probably that's why most iso-engines use half the height for one block.
Maybe use a different ratio ... for example a 3:4 if you want a unique feel.
Sorry i can't understand you, you said i no need make "perfect isometric cubes" i need make a raio 3:4 for solve this problem ¿?
And this is of the gba game in isometric uses outlines:
And this is an image of marble madnes uses similar tiles etc..:
http://www.teaser.fr/~amajorel/marble/marble-all.pngMy game is a combination of this, and arcade, you need solve puzzles(sokoban type), get keys, push bottoms, and you can change the state of the ball (solid, bouncing, buble), and you can broken "ice cubes" when you hace the solid state etc...
If i cant solve this, i simply try to evite this situations in the levels, to appears the minimun as possible.
