So, I tried my luck on the Windows Phone market, by wrapping the HTML5 version of my game in a webview. I was barely able to hit 30fps on my Lumia 530, which is a low end device, so I thought that I'm successful However, I haven't tried any other device. If you have one, could you please test my game? Much appreciated - windowsphone . com/en-us/store/app/aquatic-rescue/153fce08-de77-44ec-8138-2b0f3f1ae614 - you don't have to buy it, just use "try" - it has first 20 levels free.
