GS: Have you encountered any emergent gameplay due to the physics-based engine, ways to solve puzzles or utilize the in-game actions that you hadn't anticipated?

Sam Thibault: Tons and tons. The point-to-point beam is particularly versatile and allows the player to make a spring-like constraint between any two objects. It's great for solving puzzles, but we also had players doing unexpected things with it, like connecting two barrels together to make a nunchaku-style melee weapon. In one puzzle I built, where the player needs to rotate a conveyor belt into position, I was pretty happy when I knew of three different ways to solve it. Then testers came in and found four more ways to solve it I hadn't imagined--that's exciting!
