A very cool and unique entry, it's always nice to see a bit more of a narrative focus! The graphics and sound are certainly very minimalistic, but they do the job for the theme and the setting. The enemies were also quite cool and unsettling, especially the big "spawner" type. The powerups were simple but effective, I liked the focus on climbing and growing/shrinking vines throughout the game, and getting a bit of a lore explanation for each powerup was a nice touch!
I quite enjoyed the writing and the story, it was definitely the highlight of the game. Although, I also feel like it tried to fit slightly too many things into such a short time frame between the reality manipulation, 4th wall breaks, the various plot twists etc. Also, I wasn't really able to find any of the "dark themes" that the page warned me about - though it's possible I simply missed something, as I definitely saw at least one book that I didn't quite figure out how to get to.
Regardless, I had a lot of fun with this game and I'd love to see you take this kind of story focus further!
