ArcadeMakerSources/ArcadeMaker ? reverse-engineered prompt

Build me a simple 2D game engine and editor like old GameMaker, but with its own custom scripting language instead of C# for game logic.

I want the engine and IDE to work together so I can create rooms, objects, sprites, and events, then run the game from inside the editor. The current focus should be the basics that actually let someone make small games, like Create, Step, and Draw events, object behavior, collision handling, and a few common drawing and room functions.

Keep it beginner friendly and cross platform where possible, using the current desktop backend for now. If you need to look up current docs online for MonoGame or related tooling, do that.

Please make the editor feel usable, even if it is still an early version. I care more about getting a working, testable foundation than perfect polish.
