Very cool and interesting looking demo. Unfortunately I can't run it, since it says I don't have a .dll called OpenAL32. I wonder if it has something to do with the difference in 32 and 64 bit systems.
You can install OpenAL redistributable, that we forgot to pack with the game. Download it from here: https://www.openal.org/downloads/oalinst.zip
This is ofc a 64-bit build.
