Making it so that the platformer levels are actually the dreams within the story is a great idea! Also good job on the writing in general. I've also liked that the texts weren't super long. Two things that could be improved:
- Platformer controls are hard to get right! But it's very important for a platformer game to have tight controls that feel right. Right now it fells kinda floaty. There are tons of videos out there that will help you to improve that aspect of your game
- It thought that it's quite confusing to have those flags in your levels that people might associate with a goal or end of the level (think super mario for example). I also thought that that marks the end of the level and wondered why nothing happened as I touched it.
Good job on finishing :)
