Recently I made my first own game in GameMaker, which I have published on GX games. Before this I had used the arcade shooter template to make a game in the fastest time ever (half an hour!). This time I tried to basically alter and play around with physics and mechanics of that template to make something new. And I'm quite pleased with the result.
I have named it Meteor Defense. Check it out!

I had made this game within a day. I had only made the background some earlier day. And I did not make use of any pre-existing assets in the template as-is, all have been remade or altered. I do wish GameMaker projects could be exported too.
