matrixreal, yes thank you I have actually searched and read what I could find about optimizing for a few evenings now, and the tips are repeated again and again, but I cannot find anything in them that points at something I have done wrong in my project.,,

Events 17
No animations or effects or blendmodes, and no sprites in the playable layout above 512px, (most are 128 or 64). Only 14 of the 32 objects are instances of the same sprite (to build platforms with physics and solid) and the other 18 sprites are individuals. Only a handful of sprites are visible on screen at the same time so I do not exceed 20.
I use a Samsung galaxy tab 10.1 which is a couple of years old, but it can play much more advanced games with higher framerates and resolutions than my blocky proto-test..
My 17 events are nothing fancy, just "is touching" this or that then "simulate platform" or "set visible/invisible".
Perhaps with my limited knowledge it would be best to target PCs and not mobile/tablets to avoid burying myself in constant hardcore optimizing?
