I'm just this guy. From the USA. 25 years old.
I finally tried Knytt Stories earlier this month. Then I was thinking about making a level for it, and browsed through the forums for the game.
I came upon the topic http://nifflas.ni2.se/forum/index.php?&topic=821.0 . Someone had asked about creating games, and one of the moderators mentioned Construct, as well as Game Maker, and Clickteam's programs. If I were a member of the forum there, I might thank him.
I'm glad I gave Construct a try. I have had some problems with it, quirks or bugs, an occasional crash, but it works most of the time, and is pretty easy to work with.
I've composed music for years for fun, in tracker formats (such as s3m and it). I have also dabbled in graphics. A little in making sound effects, as well.
I have messed with game creation programs before, but never made anything serious.
I started on a game engine of a sort using C/C++, but that was doomed. I was intimidated by properly implementing AI, level loading, and whatnot. Learning the proper ways to do it, finding the right tutorials or explanations. I was too intimidated by it.
What I have with Construct so far is far more advanced, and much easier to work with.
Well, other than being unable to turn on or off MOD music channels, but other than that, it's more advanced.
I've always had fun with old games. NES, SNES, Genesis, and whatnot. I still have some favorite old games. I may not have played them in a long time, but I have fond memories of them.
So, I have began to make my own platform game. It is coming along all right. I need to just keep working at it, and add more things.
