"34BigThings is one of the biggest independent game studios in Italy. Born out of sheer passion and self-sustained throughout..." Then why are simple options for keybinds and intrusive UI toggles too difficult for you to implement? Also any dev that removes multiplayer functionality and refuses to support even LAN in "DRM-Free" releases is objectively holding out on you and deserves to be insulted so long as Quake exists.
Dev failings aside; the game is fast, fun, and gorgeous.
