In its current state, this is not a VR game. You can refer to the Steam page for this game to confirm the fact. In one of the Steam Discussions pages for this game, the devs have mentioned that the VR version of this game will be released later in this year. In its standard mode version, the game still looks like challenging fun! It also features a remix of Martika's 1988 hit song "Toy Soldiers" as the background music (See the third trailer video in the game's Steam page)!
