I think those issues where adressed many month ago... still there seems to be no fix yet. commented again, maybe it will move something...
for the other topic, pro / con c2:
I love construct. Because it enables me to live out my childhood dreams to programm games without to much learning / time investment. but construct is merly more than a tool to make very simple games or good prototypes for prove of concept and that makes me kind of sad.
at some point or another you will run into problems which you cant fix.
besites of the jitter/jank/framelags that are arround for ages whcih makes all games pretty unsmoth (a problem for every html 5 app) my curret problem is with the multiplayer input lag. for turn based games, construct is the best you can get. but for anything fast... its just not there jet.
Other problems are with audi... laggy for the first time play of a sound and several other issues (volume on android and so on)
but i really hope it will reach a point in the future where you can make high quality games with construct. and i am sure ashley is working hard on this...
i will be there to make one when the time hast come
kind regards
