SpaceEars is a sci-fi roguelite game that seamlessly combines epic space battles with functional ear training. Players fly through space, fight aliens, and recognize music intervals to progress. The game gamifies ear training, requiring players to learn different notes to activate power-ups and clear stages. It offers a unique mix of roguelite gameplay and music education, progressing players through levels and musical lessons at a natural pace.

In SpaceEars, players can venture through wormholes, defeat bosses, and collect spaceships and power-ups while improving their musical ear without even noticing it. The game provides training on ascending, descending, and harmonic intervals, allowing players to recognize intervals in a musical context, just like while playing and listening to music.
