KILL THE K.O.T.H. is a first-person adventure climbing game that gets an alpha demo that you can download over at its itch page, developed by Rubeki.
You arrive by boat with your trusty axes to a mysterious island and explore a huge tower, by jumping and hanging onto your axes.
You meet weird NPCs and embark on a mission to kill the king of this arid land and save the people from his injustice. The story unravels with an eerie ambience as you climb to the top.
