EX VITRO -Steam-

 by Alex May

EX VITRO is a dark sci-fi 2D platformer where you delve into the ruins
of a military research facility and discover the horrors within. Whether
machine, creature, or something else entirely, you’ll face the violent
legacy of the last survivors of humanity 

Nice little Metroidvania
