introduced the Game Builder and promised a tutorial series. This post is the orientation that sits in front of those tutorials: what the Game Builder is, how its pieces fit together, and why it exists. The hands-on builds start Thursday.

Draw the level, code only the rules
The core idea is that a level is data, not code. You draw it in the editor, tag each object with the numbers your game needs (lives, value, speed), and the editor saves a small .game file. The runtime loads that file and realizes it into a scene of sprites. What is left for you to write is the part that is actually yours: the rules.
The 3D editor sculpts terrain directly: height, holes, walls, pluggable surface materials, and smooth interpolated slopes, all previewed in the form factor of the game you are making.

Where to go next
The three tutorials build a real game each, in increasing order of ambition:
Thursday. . It covers the part most tutorials skip: bringing in real art and slicing an animated sprite sheet.
The Thursday after. . Cards become data-driven elements on a felt table.
The Thursday after that. . Sculpt terrain and scale up to streaming worlds.
Start with Thursday's platformer; it introduces every moving part you will reuse in the other two.
