Played the first three levels of the demo and now downloading the full version.
One thing I did find was that the even though it's not a VR game, the game seemed to be trying to use SteamVR and it wouldn't run if I had my VR headset connected.
If I disconnected my VR headset it still tried to use SteamVR but because the headset wasn't connected it produced an error in SteamVR, and the game then ran correctly.
Obviously this was in the demo, but I expect it will be the same in the full version too!
