Here are my games all made with C2. They are far from optimized because I didn't know how to do it back then. But they run perfect on new devices and if I've made a new game now with the knowledge I have I would be able to make them run really well on old devices as well. And usually when my games lag the ads are the cause and are just bad implemented by me.
Construct may not be good for really shitty devices but for all others you should be able to make even big games run at a stable 60fps and people saying otherwise are just inexperienced <img src="{SMILIES_PATH}/icon_razz.gif" alt=":P" title="Razz"> So the games below are old and not optimized at all straight from C2. I also have the games on the app store but it takes to long to update a game there so gave up iOS. If you find a bug you'll have to wait about 2 weeks for the new build to be approved by apple and on google play it takes about 5min. And when it finally gets approved you have another update with bug fixes to upload x)
