You can check out the game's game jam version over here:

The new version doesn't really expand the story, it mainly features some quality of life/gameplay improvements and bug fixes.
The CG would feature three monsters surrounding the main character, Amy, who is sitting in front of her PC. It will be used for the final scene. The art doesn't need to be colored. Simple lineart/black and white ink style art would suffice (but we can of course adapt to your preferences). I've pasted a reference image below but it doesn't necessarily have to look the same if you feel like there's a more effective way to draw it.
