I don't think my computer likes this game, because whenever I launch it all I see is this: https://imgur.com/a/2747F, and keyboard inputs do nothing. Any thoughts?

Its an interesting drawing program, but there doesn't seem to be anyway to edit or delete previously drawn items ..... I've found the 'delete last' button, but is there a way to select any item & modify/delete it ? Is there any user help files / tutorials? ...

There were some issues with the exported OBJ files. All is good now.

What's the purpose of this software?

As title says, I can't open the game in desktop mode, there is no option, it just opens as VR.
