Very cool to play a first person puzzler as old as this, before the mechanics had been stapled down. While it's built in the familiar HL2 source engine, it pulls off some really neat tricks and actually pulls them off pretty smoothly. The broken glasses that you use to look into the past and the bit of motion that they have as you move around are an incredibly neat touch. Despite ending with a "To be continued..." I don't think anything ever came of this, which is kinda a shame!
