By using pre-build behaviors\actions and more you can 'program' your game by simply 'linking' they in the editor.
Con Windows only
The editor is Windows only, no OSX or Linux versions are planned.
Con 3D features may not be enough for some users
The 3D capabilities of the engine are a bit limited (for today standards), and some of the times you'll need to work around to create something.
Con not for beginners
even those few tuts don't learn u the very basics, first u must learn the basics somewhere else (the submitted pros are by professional guys)
Con no any success/good game
just ask them about made games and u will see what they show u, if u find any it would be simple/small game or if isn't that take much much time (but if u could see :D )
Con not good performance
if u wanna use more than few actor / light / some good event, or trying to get a pretty look, u will get much drop frame rates specially if wanna move light (something like flashlight)
Con New tricks for getting more money
As it don't have enough tut, and they don't wanna make more, so they just add some new services about one on one help which that cost 40$ for a hour.
Con Small number of tutorials
Con You won't receive fixed version about bugs soon
If you fall to a bug or problem and report that as bug report, it will take about 1 week to get any answer, and if they solve that, the fixed version will just come next update for engine which that isn't soon and no specific time , so maybe you have to wait for one month.
Con some workflow are confusing
really sometimes u have to do a time consuming workaround to just do a simple function
Con html5 export is not fine
much drop frame rate, have some bug that will rune ur game, (also looks like just run on firefox)
Con No IAP or Ads support
Are you a mobile developer? If so it's good to know that it has export for ios/Android but no support for IAP or Ads
