This is the end result of me messing around with minecarts and moving floors.
The buttons change the orientation of either their nearest or their same-color track. Now I'm not asking you to solve the puzzle, but if you want to, the green buttons are linked, and you can cross the orange rock block.
Does this puzzle type have a name? I'm almost certain they exist, maybe in a grid-based game using trains instead. And how do I make these puzzles engaging?
