I tried it and the game loads, but I can't see anything. I can see the effect in your screenshots without problem. Nothing appears to change when I try to move. Here's a screenshot and below is the settings used for it. I also tried other settings, but couldn't get something that I could see. I'm on Ubuntu MATE 18.04 with Nvidia GTX 960 graphics and 2560x1440 resolution.

I see the top link (labelled as supporting Windows/Mac/Linux) goes to your website where you can download the game. You also supply a Windows link to download that version directly. Please link directly to the Mac and Linux versions too. Otherwise the game can't be installed through the Itch.io app on these platforms. Thanks!
