wow thank you very much for your critic!
that are all good points you mentioned, youre totally wright with the ads and kids game, i just implemented it so i could test how to do it, but i already blocked most adult content, there should be no flirting, religion, sex, drugs, politics etc., did you see such adds?
for the sound, the game already has sound but the apk build option i choose doesnt play them :/
im pretty sure the add's (the preloading of them) are responsible for the lagging, that game it self, without adds and complied to apk normally runs perfect on the cheapest devices i could get my hands on
thanks again!
