Two Lives Left have been posting regular updates in a thread on our forums about their upcoming game, Wheeler's Treasure. I recently got my hands on a copy of the game, and so far I'm extremely impressed. Not only did they seemingly create an entire game inspired by the Orlando Bloom water wheel fight scene in Pirates of the Caribbean: Dead Man's Chest, but they've really managed to nail the difficulty curve.
One of the things we've discussed at length during our podcasts is how much we enjoy games that foster the feeling of if you could only have managed to not make that last mistake you could have gone even farther, almost forcing you to play again to see if you could beat your previous attempt. Games like Flight Control and its associated spinoffs, Doodle Jump, and the recently discovered Boost 3D all provide this experience, and so far Wheeler's Treasure is giving me a similar vibe.
