Here is game with almost 200 events 12 event sheets and 13 levels, 2 game modes it is fast paced, I have used latest XDk 1912 , Crosswalk 12.40 admob plugin, media plugin. Turn off wifi to get rid of ads, On crappy alcatel i got 50-58fps
PS: i am using particles as well , sine behaviour, rotate behaviour , solids, local storages every ticks, every seconds , and such and you can see fps in every level
