The Dark Room is a surreal solo Firelights rpg. The closest thing I can think of to compare it to is maybe Yume Nikki or maybe Void/Tension, but this isn't exact. It feels liminal and personal, and it's about exploring a dreamscape.
The PDF is 2 pages, clean and well organized, with some really expressive and subtle visual design on the logo.
Mechanics-wise, you play by drawing cards, rolling dice, and comparing the numbers on the cards against the numbers on the dice. This system is used to generate encounters, but it's also to make checks, and it feels both swingy and balanced. Results tend towards mixed success.
The game is mostly atmospheric, but it culminates in a very cool boss fight which is always tailored to your character. It's neat to see a solo game take this angle, and it makes the game feel not just introspective but purposeful.
Overall, if you like solo games where you develop a character, I think The Dark Room can be a pretty powerful experience. It has a good atmosphere and a strong conclusion, and it's definitely worth adding to any solo games library.
