RPGAdventure by Team Undertale Yellow

Undertale Yellow is a fan-made prequel to the acclaimed game Undertale, released on December 9, 2023, for Microsoft Windows. Developed by Team Undertale Yellow, this role-playing game follows Clover, a human child embodying the trait of "justice," as they navigate the monster-inhabited Underground in a quest to return to the surface. The game retains the signature bullet-hell combat mechanics of its predecessor, allowing players to choose between pacifism and aggression, with each decision influencing the storyline and ending. Notably, Undertale Yellow introduces quality-of-life enhancements, such as the ability to run in the Overworld for faster travel and immediate retries for boss battles from the game over screen. Additionally, players can access various accessibility options, including an "easy mode" that boosts defense to reduce the game's difficulty.
