I have been a fan of TASVideos and speedrunning in general for many years, but only one game has intrigued me enough to speedrun it myself: Teslagrad.
I am overjoyed to learn that libTAS has become an accepted TAS tool and am here to bring you the past few years of work the real-time speedrunning community has accomplished with this game.
Teslagrad is a Metroidvania-style puzzle platformer by Norwegian indie game company Rain Games. It involves using the polarity of electromagnetism to manipulate objects and to levitate. You also collect a pair of boots which allow you to teleport a short distance through obstacles, an ability which we have exploited to skip several portions of the game, including mandatory collectibles and two of the boss fights.
I admittedly have never been a good runner of the game myself, but I have enjoyed serving as strategist and scribe, formulating some time savers and cataloguing all of our knowledge into a dedicated section of the Teslagrad wikia site. Most of our tricks are accompanied by video clip demonstrations. The things we have found are too numerous to list here, so I encourage anyone interested to visit: https://teslagrad.wikia.com/wiki/Category:Speedrunning
