Hey, just a quick note, the macOS version is having some issues on High Seirra. The included game file didn't have it's file permissions set to run, so I ran
chmod a+x RGBBlaster
but it still wouldn't run!
I get the error message indicated above.
Ouch!
I'm not a mac user. I tried the exported binary (it's really a .zip but with execution permissions) on a friend's machine and it worked fine.
I'll check it as soon as I get my hands on my friend's machine again.
Edit: I've uploaded a new zip. Uncompress, and click on the RGBBlaster file. It should work now.
