I'm trying to learn and figure out the best way for me to make games that work on the web, especially on mobile devices. This demo was created with vn-canvas (MIT license, via Sourceforge) and contains a menu as well as a brief sprite animation. It works on my Windows 10 Desktop PC, Chrome or Firefox, as well as Macbook Pro, Firefox, Chrome (not Safari) and iOS 10, iPhone 6 - Chrome, Firefox and Safari. So for my devices, it only failed on Safari, Macbook Pro, running El Capitan.
It also didn't work on my SO's iPhone 6 Safari, or iPad
