I'm glad you like the game! Please, send your construction(as a sketch file) to me, I'll take a look. (How to save your construction as a sketch file => In settings, select Toolset = full, then on the toolbar you will see a V-shaped button (You may need to switch to full-screen mode to see the button). Click on the button, it opens a popup menu. If you select "Export to JSON", then your browser downloads "sketch.json". Please, send this file to sdkgames@proton.me )
