Go To Hell is a skill- and reflexes-oriented puzzle game by Metasauce, creator of Hex Empire. One part digging game, one part physics playground, the title welds the two elements together into a tightly-structured experience that's as intriguing to play around with as it is to beat.
Hex Empire is a casual turn-based strategy war game, occupying a comfortable spot between the simplicity of Risk and the number crunching of the Avalon Hill-style board games that inspired the whole soldiers-on-hexagons thing. It lets you jump right into battle without much fuss, and offers enough tactical depth to be addictive even after several wars have ended. A bit of a treat, really.
