Thanks for the quick replies, guys! We're still busy making a crapload of assets for the game anyway so there's time enough to hopefully see C2 expand further and hopefully be able to support this project as I really am not up to bothering with GameMaker since a lot of the features that we can easily do in Construct's event system requires GML there and I really don't feel I'm cut out to be a programmer.
It'd be nice to be able to represent Construct with our project since this has got to be hands-down the best WYSIWYG IDE. If C2 ever gets to about the exact same features as CC is currently at or surpasses it even and can totally handle large desktop games through HTML5, one probably wouldn't have to look anywhere else and it'd definitely make quite an impact on things.
I was formerly under the impression that HTML5 was just going to be limited to mobile games and it'd be stuck competing with nothing but Angry Birds, Cut The Rope and the like. From what I've been seeing though, perhaps HTML5 really will overthrow Flash in almost everything it covered. If Super Meat Boy, Castle Crashers and Scott Pilgrim vs. The World: The Game were all done in Flash (I may be wrong on the last two), then with enough time HTML5 may just be able to do that as well.
My thanks again, Ashley, newt and wilfryed!
