Inside a Star-filled Sky

Inside a Star-filled Sky is an infinite, recursive, tactical shooter by award-winning designer Jason Rohrer (Passage, Between). What if you could enter an object in a level and find a level inside of it? What if you could enter an object in that level and find another level inside of that?

What if you could change an enemy or a power-up from the inside? What if you could enter and change yourself? What if these levels inside levels inside levels went all the way down---and all the way up?

Inside a Star-filled Sky is a hard, procedurally-generated shmup built around this core concept.
