Steam is only required for the multilayer part. The slippery movements you mentioned are abit awkward, but can be lessend by turning off head bobbing. Long install is due to the game is about 10gib in size. I thought the lighting was great in this game, especially with HDR on. There some nice stained glass windows with transparency and refraction in the game that look cool and maybe TDM could take inspiration from? Also theres some nice volumetric lighting effects that cast coloured light rays through the windows close to the end of the game that look awesome, even if its is fake volumetric lighting. The body awareness is great for adding extra emotions and communications throughout the game, even if you cant control it.
