roguecore, in my experiments, I mean, I made an android apk exporting to cordova and using intel xdk.
I noticed that in my game Zuper Alien World running on my old cellphone (from 2014), it gets an average of 40 FPS and 80-90% of CPU usage if the game has more than 100 objects, sometimes it gets 100% of CPU and the FPS goes down to 20 FPS. when I start to get coins, and destroy some enemies and blocks, the object counting goes to less than 100 objects, then the CPU goes to about 70% and I get 50-60 FPS.
In the same game, on my older tablet (from 2013), the perfomance only gets better when the amount of objects go less than 80.
the game that I mention is this one:
but running the game on the web, the performance is better, different when I run it as an android APK as I mentioned.
