While there are seven characters to choose from in The Cave, only three may venture into its depths at any one time - and once they do, you'll discover a treasure trove of delights. In an early part of the game, after jumping over all manner of obstacles, the characters eventually reach a fragile bridge. The Cave's comically mysterious personality warns that "if you break it, you buy it", but with no other way forward it seems like the only way to progress. Nervously leaving the first character standing on the bridge, you slowly urge the second and third to step on board - and once they're all on the bridge it collapses, plunging your chosen trio into the depths.
These adventure puzzle elements are the core of The Cave. While exploring the various underground landscapes requires skill, finding the solution to the various riddles provides the real challenge. Each character also gets their own personal story, revealing the horrors of their lives.
Remember though, while these tales are personal, none of them can be completed alone. Calling on new-found friends is often the only way to overcome a problem. The Twins prove especially twisted, as the Cave itself points out: "when has there ever been a pair of twins who weren't evil!" With seven characters to enjoy, there's a lot to keep you coming back to The Cave.
