Only Up, the ultra-challenging, physics-based indie game, has been removed from Steam by its creator owing to “stress.” Created by SCKR Games, Only Up was previously removed from Steam amid accusations of copyright violations connected to various in-game assets. Immensely popular with YouTubers and Twitch streamers, partly because of its intense difficulty, the creator of Only Up has now delisted the game from Valve’s storefront, explaining that they “made a lot of mistakes” and wish to “put the game behind [them].”
