Play Mario in the Castle of WTF 2 Online

Mario in the Castle of WTF 2 is a fan-made Super Nintendo Entertainment System (SNES) game released unofficially in 2024. It was developed by a small independent creator, though no major publisher was involved. The game fits into the modern homebrew scene, where enthusiasts craft new experiences for classic hardware, often pushing the system's limits with unconventional ideas.

You control Mario through a series of surreal, glitch-inspired levels inside a distorted castle. The main goal is simply to survive each screen and reach the exit, but nothing behaves as expected. Platforms vanish and reappear at random, enemies move in erratic patterns, and obstacles materialize without warning. The pacing is frantic, with constant surprises demanding quick reflexes and adaptation. It feels like navigating a digital funhouse where every step could lead to a trap or a breakthrough.
