well you have unlimited possiblities because not limited sprites and this is full game so cool features can be implemented. For me more features + interaction = better (most full games is just bunch chars and staged from one creator/team with only few features which make true full game). I know i isn't actually suggestion but I hope opinions are allowed too.
