Building on the massive success of Cave, this version introduces many new features to enhance the game for both gamers and distributors. Cave is a game where you control a worm as it navigates it's way through an ever narrowing cave. Avoiding obstacles and the cave walls with a very simple control method made for a very addictive game. Cave 2 introduces the 'Collector' game mode. The same basic principle applies, but this time you can make things easier for yourself by collecting the rings as you go. For each ring you collect, you will be rewarded by the cave narrowing less slowly, making it easier to progress. However, you must judge carefully which rings to collect, as some are placed in difficult positions, and attempting to collect these will make things harder, not easier.
