Ghost Song
With deep inspiration from the Metroid series, Ghost Song creates an atmospheric action-adventure with countless corners of an alien world worth exploring.
Next Space Rebels
Next Space Rebels gains altitude as a rocket building simulator with an enjoyable trial and error loop. But it plummets back to earth as a politically-charged FMV mixed with a visual novel based on ownership of space and the internet. Great if you're into that kind of stuff, but better left out of this world if you aren't.
