I have a Linux VM on my Windows machine and I tried to give your game a go, but I couldn't get the AppImage to run. Would have loved to try the game, though, as it looks interesting :/

Hello and thank you for trying Lambda Lantern.
If you'd like to try again, there are some updated AppImages located on the GitHub releases page.

Not sure what Linux VM you're using but they work with Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, Arch, and many more.
