Alright, sorry for necroposting but I think all of the other topics are also old so I'll just have to bring this one to life.
I have just played W.I.D. and it was a great experience... all of the cutscenes were well made and the story itself was excellent. Only thing that did bother me like how other people "might" comment about it is the lag and the bugs in the game. I am actually sad to hear that Colt himself said that "it was a waste".
I have played around with IGM for a bit (Indie Game Maker but Action Game Maker before) and all I can say is that it's quite confusing. And seeing how not many tutorials and resources and games have been developed with the software, many have been saying that IGM was somehow a "rushed" product of enterbrain and which is why its not so popular. And somehow many of my friends also didn't like it that much either but sticked to RPG Maker.
I'm not saying that I should discourage you to use IGM. But think of the flaws of RPG Maker XP that had affected the gameplay of W.I.D. I mean you can still take the risk of using IGM and maybe produce a great gameplay or still get the same but improved results like that of W.I.D. XP.
So here I can also suggest using other programs like Game Maker. Most people use this program for metal slug like games or even castlevania console games. Or maybe ALL game genres in general...
We can take a look at this for example (I'm 99% sure you've seen this too

):
Well also, the disadvantage when using GM would be script errors as well

. So unless you're a really experienced coder, I REALLY suggest W.I.D. for Game Maker. The results would be the best and smoothest gameplay that you'll ever achieve (At least I hope so...).
ALSO,
I've checked your deviant art profile and have downloaded every art and drawing you got there:D. The first comic strip you made for WID was great!
