Bought it cause a friend recommended it to me. Released in 2009 and running on the Source engine, Zeno Clash has melee combat that is janky as FUCK and was really only developed by four guys who were just artists. It's short and runs on the Source engine so of course it looks absolutely awful in terms of texture quality.
Other than that, the game's fun. For how broken and frustrating the combat is, it's still enjoyable. The artstyle is also really unique and cool looking. Voice acting is so amateurish and bad that it's good. Devs went on to make that one puzzle game with the god boulder or whatever it's called, made a sequel to ZC and then proceeded to milk the rock game on behalf of Sega. Shame.
