Gamemaker: Studio is like a big box of toys that helps you make your own video games! It has lots of tools and ready-made things that you can use to create your own game world.
It's like using blocks to make a castle, only instead of blocks we have different things we can use like pictures, sounds, and characters. We can put them together in different ways to make our own game!
Gamemaker: Studio also helps you make sure things work the way they should in your game, just like a grown-up helping you make sure all the blocks are in the right place to build a sturdy castle.
Once we've made our game, we can share it with our friends, who can play it and have fun too!
