You may not know this, but Pixeljam (makers of Last Horizon) have made a lot of games. One of them you might recall was called Dino Run. Well, as of last week, we started a campaign to create the sequel:

We're making the game in small stages, and using contributed funds to support the development of each stage. Funders get everything we create during the process: concept art, music, prototypes, experiments, alphas, betas, and eventually the full game.
If this is something that interests you, please consider contributing or spreading the word. Every little bit helps!
