Well with all this i have:
Shadows only down of objetcs, etc... and with 2 types blocks and the shadows with 2 colors.
if you include some nice textures, the textures would help show the different levels.. for instance, one texture like a grass would have grass blades falling off the edges, which would help show where the edge is.
so, id suggest includeing some good textures which would help show the edges of the surfaces, because how you texture and edge is different than textureing the middle.
Yes i know with good textures, more colours etc...i can make the perspective and the level more good and minus confused, but for the moment i will try to make all the game with low detailed/low busy
.
I making this not for a pay mobile game, i make this to learn and get the dinamic to make a mobile game, and well, when i finish i put screnshot and make a litle demo with 2 o 3 leves in 3 formats (128x128 / 176x208. and th other big resoluction i not remember now) and if any company like it and is interest i can improve the quality
