Hello my friend.
To be honest, most of my games are made with GameMaker, GameMaker is
awesome game creation tool, and of course Construct 2 is the best too
so far in the HTML5 field, both engines have their pros and cons in
For the Pros of GameMaker 8:
1- Got GML (scripting)
2- Room Editor
3- Support Tilesets
4- Support Sprite Sheet (PNG)
5- You can Extend it (DLL/GEX)
but for GameMaker Cons:
1- Despite the support of Drag-Drop you still need to learn GML, which
may not friendly for non-programer users for good functions.
2- Screen Tearing Issue.
3- Can't resize or rotate sprites and object images inside the room
4- for HTML5 version, don't support WebGL (Yet)
For Construct 2, the Pros Goes:
1- flexible without programing for most part of features.
2- the game programing via events style, which is very organized and
fun to create.
3- Can rotate and resize object sprites inside the Editor, like send
object to front or back.
4- Support Behaviors, like platform which can easily applied.
5- Fast Fixes and Frequent Updates (Thanks to Scirra) for bug fixes and
6- Support WebGL for HTML5 (fast performance)
But for the Construct 2 Cons, we have:
1- Can't Support Scripting within IDE, (although indirect you can
use the C2 SDK).
2- No Tilesets supported (Yet).
3- Can't copy Layout (Yet)
That's all so far, but one thing made C2 so unique is, you can import
GM HTML5 sprites and tilset to the layout !!
it's like, C2 is your second wife that don't mind to befriend with your
first or ex-wife(GameMaker) XD (just a crazy example)
the Both engines in my opinions are great, and if you can get them both
i see no problem with it, but if you deciding which one suitable, just
give them both a try and good luck <img src="smileys/smiley2.gif" border="0" align="middle" />
