We strongly recommend playing the game through Unity WebPlayer on a supported browser, but for those of you who really want to play through Chrome, here’s a temporary fix (as of 2015-08-10) that will work until support is dropped by Google altogether.
1. Type the following into the address bar: chrome://flags/ #enable-npapi
2. Select enable under Enable NPAPI
3. Restart the browser (only fix for the out of memory message)
4. Use different Internet browsers. (Internet Explorer, Firefox, Opera, Chrome)
5. Make sure your browser is the latest version.
6. Make sure you have the latest version of Unity (https://unity3d.com/get-unity/download). Your Internet browser will automatically use WebGL as an alternative if Unity is not installed.
7. Clear your browser cache
8. Clear your cookies
