As others have pointed out, your mistake was trying to develop a graphics-heavy game with the wrong toolset. I'm one of the devs that works on the Android and iOS apps for lichess.org and we've had a lot of success with Cordova/PhoneGap. It's allowed us to do all our development once with occassional workarounds needed for platform specific issues.
