Dwerve

Dwerve is a tower defense dungeon crawler RPG where you play as a young dwarf tinkerer who adventures into a ruined kingdom and unearths the lost technologies of the ancient warsmiths: turrets and traps. These are the only weapons that can protect the dwarves from Witch-Queen Vandra and her army of bloodthirsty trolls and monstrous creatures hellbent on conquering the surface.
