Raven-Star is a 15 minute, easy platformer centered around the interesting story of a wingless raven on its quest to get wings from a fallen star. You begin with the ability to run, before acquiring the ability to jump, followed by gliding. The most common foes are spikes, but since the story is the interesting thing about Raven-Star, you'll be hunted by a shadowy figure of either doubt or mockery questioning what you are.  Each defeat respawns you in the same room. There's also construction going on with hard-hatted pacing that can be used for hopping on.

It is a brief experience, but still engaging.
