Developer Joshua Gump (Heliocentric Studios) informed us that Gran Vitreous has been released on Steam:

Gran Vitreous is a twin stick shooter in space with the added mechanics of a loot based Action RPG. The areas that players battle through are randomly generated filled with zones containing different encounters like boss type enemies or space debris/asteroids/gravity-wells to avoid. The equipment is all loot based with 3 weapon types, utilities, hull, and shields. The ship also has a passive skill system that allows you to upgrade and add abilities as you level up.

GenEnemy published a nice gameplay video on Youtube:

You can get this game for a fair price on Steam.
