Jewel Thief was a game made by Paul Ligeski from ServantWare in 1991. This app is a re-implementation for modern hardware by Christian DeTamble of The Refactory using the original sprites and backgrounds.

The National Museum is in a tissy. The country’s jewel collection has been stolen and scattered all over creation. Your mission is to travel to far away places and steal back the jewels from their unrightful owners. As you leave your mother wishes you well and reminds you to be careful… Collect all jewels as fast as possible and avoid guards and borders. You get extra men when you collect jewels. Tip: Use only one finger to move around.
