"A Lode Runner Story" takes the original gameplay mechanics from the original game and adds in a number of RPG elements such as NPCs, skills, quests, and items. As you play through the game, you will control the direction of the storyline via your interaction with the characters in the story. The dialogue paths you take, along with your behavior in the world, play a big role in determining how the story unfolds.
Currently the project is about 6 months into development. Many of the game's mechanics are in place, but I have not yet released an actual playable demo. If you're interested, you can view some "developer diaries" that explain / demonstrate some of the game's features.
