Hi Kate. Would definitely suggest Tales of Escape (6 player multiplayer) as an escape room option that you can sell as team communication/teamwork. There is only 1 map available as part of the Springboard license and I have been pushing for Springboard to try to get them to add access to the other maps as well for us. There is an issue with setting up private games (conflict with SpringboardVR controls) so you have to go through a public game setup.
Another suggestion that I have been given is Fantastic Contraption - puzzle solving VR game. I contacted the developers about getting them onto SpringboardVR and they emailed back this morning saying it should be on SpringboardVR now (and is listed as such on their steam page). Can't see it there yet so hopefully soon.
Would recommend Smashbox Arena as a good way to finish...
