Sleep Is Death has arrived on Steam, and we're infinitely happy. That's because Inside a Star-Filled Sky ($8) is a shmup that happens to explore the idea of infinity, letting players journey into enemies, power-ups and even their character, which all become new levels -- all with more things to transition into and out of.
If it sounds different and, well, kind of weird, it is. But you can find videos that do the best job of explaining its unusual premise at the Steam store, reachable via the Source link below. Just don't get lost in there.
