Thanks for the feedback! Regarding the length of the game, this was made for the Two Minute Horror Jam, so we were very limited in the amount of content we could include in such a short amount of time. We do plan on expanding on the story in the future! Also the enemies didn't spawn randomly, they always start in the same spot every round. Sorry if it did seem random.
About the issue with the note, I didn't see it happen in your video, so I don't quite understand what it looks like. Do you mean you weren't able to exit out of the note, or was there a delay in being able to close it?
Overall, I'm glad you enjoyed playing it!
