for me the main problem is the exporter options... There are different web app that you can make your app and export (search on the web) and it works because the export works, but you can't make advance stuff like in construct2... and you have to pay with a subscription....
now, I think the most users are worried because with construct2, they had a lot of problem to export (different bugs, performance problem...etc) everything depends by third party plugin... so, if we paid 100$ a year, do will have the same problem? I mean, you pay for using a software, but if the exporter depends by the third party doesn't make any sense to me...with construct2, you paid once, and you wait for the update, wait for the third to solve the problem... but you paid once...the software is in your computer... what if you paid and when is the time to export there are different problem? that doesn't make any sense to me...
so, I think they find a good way, because if construct3 will have the same problem, nobody will pay for something that doesn't work really well where there are similar web app already here that doing similar stuff...
so, I'm pretty sure Ashley solved this, just let's see, I'm pretty sure everything will works better than before... nobody will make a new software for make a big mistake and lost costumers, maybe it was better if the first news was something like a video or show some new feature for make more hype, let's see, I can't wait to use construct3!!!
