The Ballad of Deadeye Chambers

Don't get too close to enemies, their melee attack is a one hit kill after a split second grace period. 

There's no intro scene so the story is you've been killed and woken in a strange place, an underworld level to teach the basic mechanics.

There's no pause menu either so to exit you'll have to die or win to get back to the main menu. Also, the enemies might bug out and not die sometimes and one green guy walks on air coz his navmesh didn't work properly.
