First of all a big THANK YOU to the developers for this move.
I'm brand new to ge and find it great. I made my choice on ge because it's free from A to Z and no coding to start. Now I realize it's free since just a few months.
So I just give a few impressions from a newbie perspective:
I thought 1.5 was under development and gave a try but since you cannot export your game (at least from Windows), files are not back compatible and you have annoying icon near texts I gave up and came back to 1.4 too.
1.5 beta must do, at least, the same as 1.4 (except if it's a rewrite).
I use Windows 8 64bits and I don't get the fuss about it, it's just windows 7 with a useless start panel I removed right away.
On Mac OS X 10.5.8 my little test game hangs for no reason and now I'll try on android, I guess there are some glitches calling for fresh blood.
It's a hard but promising move to go free and further more open source. You will definitely gain a community but I think a few more steps are needed to fully get the community coming:
First, you need to explain how to build from source and how to remove the splash screen, people will add your logo wherever they want. This way you'll get references bringing more cust... developers
You should explain your bold move to open source and put your donation button on the very first page of game-editor.com
You should also explain how to expand the software (through API?) cause people may, for instance, want to go html5+js (which is getting huge now).
Flash is obsolete (as stated by Adobe), it was really good and I used it since 1999 but now? You have WebGL, javascript, css3, html5 throwing browser based 3D FPS! https://developer.cdn.mozilla.net/media/uploads/demos/a/z/azakai/3baf4ad7e600cbda06ec46efec5ec3b8/bananabread_1365612639_demo_package/index.html
I think you should add an export (in a 1.4.1 version) to go "phonegap build" because your software is tailored for mobiles and tablets.
Sorry for the number of "you should", it's just that I wanted to share what I find great in ge and the potential I see for it
Thanks again
