Small warning to people near the end of the game, Do NOT enter the area past the Alien Queen if you plan on hunting for CGs afterwards. For whatever reason it locks you in the Samus Suit even if you haven't put it on, I tried this with two separate saves, one where I grabbed the suit and one where I didn't. Now on each save if I go to previous areas and take damage instead of getting the "Damaged" CG appearance for those stages (Tentacles/plants/webbing/latex) I get the appearance of being damaged in the suit, even on the save where I never put it on. My advice would be avoid the robot area past the queen until its finished.
EDIT: Almost forgot to say, I LOVE this game, kudos to the creator you've definitely earned a new patron.
EDIT2: One of the images for a creature in the Demon Area is missing, so save often there. However if you feel like messing with files, you can find her image on a gallery site (I used E Hentai), and just put it in the "Battlers" Folder with the name "Demon Gemini Fruit (1) the second version is already there so you can find it to know which image you're looking for.
