Atnas: it is not ignorance that gives you this impression Atnas.
basically it's because this has an horizon which consists of of perspective lines converging in a point, and Snake's mockup obviously doesnt have converging lines, since it is tiled. In the case of snake's mockup this is even more evident because his paralel lines are so close to the horizon and are so vertical, making it quite obvious that they cannot converge at a point so close by.
Snake, what a great idea for a game....what is it a Save-em up :p ? a platformer of sorts? survival horror? IDK but it sounds great.
I can imagine the rush of getting to the next shop to get some batteries while saving all the people in need inbetween, but if all you have to overcome is climbing up and down a broken piece of cement I cant imagine it being much fun.....would you use only traps like crumbling floor or falling rocks? or would the hero have some kind of opposition?
Eitherway, it sounds nifty. You should grab a gamemaker and make it.
Ptoing: what in Snake's statbar would require that many sprites? Color-wise I can only count up to 4-5 necesary sprites in a scanline, So I'm guessing that each 8x8 tile would be counted as a sprite...therefore it I guess it must be a matter of how big his sprites are. Is that the case?
