Just do what you can frank. I won't be unhappy in the slightest if I don't get dat Cream ass in your game. Just being in it in the slightest, or even just so much as you thinking of it - is enough for me.
Also, I don't care how I look, since I'm assuming its your graphics that are limited and not text, so hopefully butts and buttsex aren't impossible to put in. It'd be a pretty shitty engine if text was limited.
