Crystal Mines is the adventure of a ore-gathering robot through a dangerous mine full of pitfalls and indestructible monsters. Your goal is to gather Starla, but doing so requires the player to navigate a serious of complex traps and puzzles.
It is widely considered the best game Color Dreams ever manufactured and spawned two sequels.
When Color Dreams shifted their development plans and started working on religious games, Crystal Mines became the template for two different Old Testament-themed games. Exodus: Journey to the Promised Land and Joshua & and the battle of Jericho have near-identical gameplay, save for very minor stylistic changes.
