We greatly appreciate the kind words and feedback! We decided to keep the game more "closed off" to avoid loose ends, but we did consider adding more levels, mechanics, story, and even a system to interact with papers to expand the lore. Since that would’ve required more time than we had, we chose to focus on making something more compact and polished.
That said, after the evaluation period, our plan is to revisit the game: improve it, expand it, add more challenges, and even increase the difficulty.
