I was a fan of the first day, the tentacle was on earth, and from the graphics I've seen, I think I'll also like the return of the slimy "monster".
But when I tried return-of-the-tentacle-linux.zip and started the 64 Bit version, I got the error

My laptop has no special video card, it's a plain Intel and I am running the latest Mint 19

I do not have a AMD Vulkan or so. Is this game just running with Vulkans?
