About This Game

Interstellar Sentinel is an action-packed shoot'em up that takes you on a sci-fi fantasy journey through legions of monsters, demons, and cosmic mind-ripping entities.

An inspired love letter to some of the best side-scrolling games ever made

I grew up playing games like Salamander/Life Force, Gradius, R-Type, Super Aleste, Einhander, Ikaruga, and more. Interstellar Sentinel features tight controls, digital & analog stick (PlayStation & Xbox controllers verified), stylized beautiful art with lite anime inspiration, and a rewarding experience that becomes more challenging as your skills grow.

Designed For Flow State Gaming:

Also known as being "in the zone," refers to a mental state where a player is fully immersed and intensely focused on a video game. In this state, the player experiences a seamless and effortless gameplay experience, losing track of time and achieving peak performance. It is characterized by a perfect balance between the player's skills and the game's challenges, resulting in a deeply satisfying and enjoyable gaming experience.

Monster Trophy System

A hand-crafted dynamic difficulty system. This system provides gameplay depth, layering, and secrets the more your skills with piloting and weapon systems improve!

  • Earworm Original Soundtrack:

  • End Level Ranking System:

  • 7 possible ranks from D to S+ tier ranks that drive dynamic challenges, minibosses, and may even unlock the secrets of the universe
