Buy Inside a Star-filled Sky Cheaper!

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.

Key features:

• Unique recursive gameplay
  
• Enter things---enemies, power-ups, and even yourself---to alter them for your tactical advantage
  
• Procedurally generated levels, along with a massive bullet combo system, offer limitless tactical variety
  
• Dozens of ways to approach each challenge---reflex your way through, blast your way through, or think your way through
  
• Dynamic soundtrack is procedurally generated based on moment-to-moment gameplay
  
• Plant your flag throughout an infinite level space to mark your discoveries, and see flags planted by others via a global flag server
