One Single Life is a concept game by Fresh Tone Games. The game mechanics are similar to Canabalt, but there is a special twist, that games usually tend to avoid: You only got one simple single life. If you loose it, you cannot start the game again. Really. This leads to some very interesting shifts in the experience of the player. The game actually feels like having a round of Parcours, but in a game. Before you jump, you can practice every level. But when it is getting real, the adrenalin rushes into the veins. To achieve this thrill with such a minimal casual-game… Well, that’s something I call something. Best try it out yourself. At least this game is a free download. (via)
Unfortunately I got lost in level 6!
