Necrosphere64

Necrosphere64 is a short, minimalist Metroidvania that uses 64×64-pixel graphics and two-button controls; neither button makes you jump. Dying is a core mechanic, and you respawn instantly.

Exploration and challenges

The game takes about 2–3 hours to complete. You collect items and power-ups and face bosses. Its difficulty is hard and frustrating by design.

Speedrunning and music

An in-game timer and almost no RNG make Necrosphere64 suited to speedrunning. The game features a bespoke soundtrack by Patricia Taxxon.
