The Messenger is currently free on Epic Games. It is a modern nod to the classic 8-bit and 16-bit sprite games of the past.
The game’s DLC, Picnic Panic, is also free.
Description from the store:
As a demon army besieges his village, a young ninja ventures through a cursed world, to deliver a scroll paramount to his clan’s survival. What begins as a classic action platformer soon unravels into an expansive time-traveling adventure full of thrills, surprises, and humor.
