Just finished programming my first game in Game Maker Studio. Feel free to try it if you use Windows (if you don't, it won't work). It might not work even if you do have Windows. Who knows!? But if it fails, would you mind sending me either a picture or a description of the error? It's a small install (15 MB) that can be easily removed.
This is a side-scrolling shooter similar in fashion to Gradius or R-Type if you like oldies. All of the art, music, and sounds are mine. If you're a good gamer, you'll probably finish it in 5 minutes or so. But I've no earthly idea how others will play, so take that recommendation with a grain of salt.
