what headset are you using? you could try starting SteamVR first before starting the game
also, the game comes with two EXE files, "Doubleshot.exe", and "Doubleshot.console.exe".
the console.exe version has a console that opens alongside the game and provides logs and stuff
if you could open the "Doubleshot.console.exe" version, and take a screenshot of the text in the console, it could maybe help me figure out what's happening. thx!
you can use ctrl + scroll wheel to zoom out on the console btw
