I'm developing a simple-fun arcade game for the kindle fire.
1. If you are using cocoonjs, do not use too many tiled backgrounds! After trial and error, i found out that was the biggest performance hinder. Not sure if CocoonJS needs to optimize tiled backgrounds.
2. The accelerometer is not working on the kindle fire, using cocoonjs. I get no data out of it. I checked all the expressions, and the only one that fires is touch.
