Whenever I go into a game's room and interact with the object so the actual game launches, nothing happens. (For example, I go into the "Walk" game room, and interact with the vending machine by pressing "E", nothing happens), the games aren't launching, same thing happens with all the other games/demos. Any help with this?
Tallyho friends! I'm in the process of creating my own physical versions of these wonderful discs, and on the site it's claimed the 2021 disc size is around 4 GB. When downloaded it's 5,13GB (not unpacked). Is there a way to fit this onto a DVD-r or is this just too big? Can I perhaps split it up onto two discs somehow? Thanks!
Edit: I ended up splitting the zip file into two archives (which is surprisingly easy to do with the command line :o)!
This game has been such a fun time and I've been slowly getting through each demo and enjoying them throughout!!
The only issue I've had is that Mummy Sandbox won't launch. I've tried from the hub and from the freeplay and it just pops up saying it'll launch but doesn't. Any chance someone else has had a similar issue and knows how to troubleshoot?
