Please try this link with Safari: https://ante-anima.herokuapp.com
It is the same version available on itch.io now but fixed for Safari. It should load on Chrome as well, but on Chrome/Mac it takes a few minutes to start, so better use Safari.
Thank you!
Unfortunately, Google still hasn’t updated Chrome to use Metal for shaders. You can work around it, if you start Chrome from the terminal (command line):
/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --use-angle=metal
This way, the game shall work from itch!
PS: Please first quit Chrome before starting it from command line.
