Hiya Cecil,
Our experiences work in non-VR mode. To start in non-VR ensure that SteamVR is disabled, and it will automatically launch in 2D mode.
While we don't address each question (we should) we have been patching crash issues and most have been fixed. Make sure to launch Holodexxx through the Itch.io launcher so they always stay up to date!
Hope this helps,
Mike
