Well after doing some research I've found a consistent problem when It comes to construct and exporting to mobile devices the performance is terrible which is the main platform I want to develop for. In that aspect I've found users saying stencyl is better but for pc construct dominates that realm. Is the mobile performance really that bad still?
Saddly the answer is yes !
construct 2 is fast for develop and you can do a job as 10 man by yourself
but when you want to export to mobile then you need to do optimize and it take so much time
and I guess you can not test this in free version !
Our best option for android is intel xdk + crosswalk
and this add +150 mg ram and 30+ mb apk size!
but if you even try c2 you will love it and always come back to it!
