I put together a minor puzzle to figure out how to use the game engine when assembling these puzzles properly. This little demo is missing the UI elements for the elevator and the big movable container lift. Hard to recognize them as such since this is all just boxes. But those UI elements would tell you what keyboard keys you can use and some hints of its effect.
Lots to do still. Create more puzzles so I can figure out the rest of the mechanical problems and bugs. Then just churn out these puzzles and content like there is no tomorrow.
