Instead of MMF2 (Never used it) I was fed up with Game Maker. Too confusing for me, and the community (YoYoGames) weren't friendly at all. I just tolerated it and tried making my first game, Pulse's Antivirus.
I found Construct a little later off of some site called Pixelprospector, showing games that were made in it. I saw like 2, but overall I wasn't too impressed, until I saw The Iconoclasts demo. So I learned about it further, and I'm already like 30% done with my first game! Whee!
