I like the idea of this being "What if Yume Nikki was a 2D platformer", and it does have potential for bizarre horror. It's a shame how short it really is. I do think the gameplay could've used more polish as it's easy to get stuck on the side of the wall, and I couldn't fall asleep a third time because it wouldn't let me click the button, so I got stuck until I pressed enter. I also wasn't a fan how the visuals looked, though I guess they work in context of a dream.
I appreciate you making this cos again, this concept has a lot of potential and could really work with more dynamic level design.
Hope the grandma is doing well.
