It depends if you're Windows or Mac - but the files are available above - just click the 2nd blue download button if you're on Windows or click the 4th blue download button if you're on Mac. You should see nuerolink in the filename.

neither of the 2 options for mac download seems to be loading. I just upgraded my computer and was excited to play the game with better frames. But it doesn't load weirdly enough, it is stuck on this gray screen every time on startup
EDIT: it actually shows the made with unity animation then stays on the gray screen
