Enigmoon

Commander Trevor is stranded on a strange moon surrounded by hostile creatures. He must survive, uncover the secrets of ancient technology, and find a way home.

The game is a 2D Metroidvania platformer built around exploring the moon, navigating platforming challenges, and solving puzzles.

Oxygen limits how long you can explore, making it a resource to manage as you progress through the environment and face its creatures.

The supplied reviews praise the pixel art and point to some enjoyable early puzzles, with one reviewer also seeing promise in the oxygen mechanic. Several reviews criticize oxygen pressure for interrupting exploration, along with clunky controls, limited guidance, and the game's stalled Early Access state.
