Never mind the 0.1 hours on record, I've been using the GameMaker since 2005.

Greatest tool to make 2D games with so much less overhead than other engines offer at the moment.

Believe me, because after being an indie games enthusiast for some years, I've built my console publishing business from scratch on this engine, pioneering such obscure things as publishing on Xbox with UWP. As of 2022, GameMaker's bigger than ever in its history. If you're into 2D games (and you really should be, before going 3D), check it out.
