A single developer, recently finished the game Sunstorm after a 6 month development. He has been trying to finish a roguelike since 2012. Most of his games require Python
Legends Not really a game. What it does is generates a worlds history based on an amount of years that you input. It generates a few files so you can look for specific things.
Idle Hero A game where you hardly control your character. It is all text based and you can watch as your guy runs around a dungeon and kills things. A very short game.
Sunstorm His first roguelike, it features 34 dungeon levels with several realms, hundreds of monsters and items and a few classes.
