- Advanced Batch Scripting: Write entire logic chains using multi-line inputs. Press
Enterto stack commands and execute them all in a single compilation session. - OS Integration Sandbox: Safely interact with your host Windows OS directly from the in-game terminal (generate text files, manage clipboards, or summon diagnostics).

Hey guys!
First of all, a massive thank you to the first 5 people who downloaded the game. It’s incredibly exciting to see your interest!
A quick heads-up: I accidentally left an important feature out of the initial manual. You can press F10 to inspect the selected object. This will instantly display its exact X, Y, Z coordinates, size & rotation. It’s higly useful for terminal routing and precise sandbox manipulation!
Please use this thread to drop your thoughts, bugs, or any feedback. I’d love to know what you think!
