Blight Dream
Blight Dream is a freeware 3D semi-horror exploration game by Kanawo (Teriyaki Tomato) made in Smile Game Builder.
It takes place several years after Blank Dream, but is not closely related and can be played independently of it.

She eventually learns to preserve them using a notebook, but becomes curious about the gap in her memory following the accident. Michiru starts to look for clues around the house, but it seems her brother would prefer that she didn't...
