The developers of PonyKart have released another amazing video, showcasing some of their most recent changes to the game and some rather nice-looking concept art. It's quite interesting, and I must say that they are making great progress on their game. PonyKart is shaping up to be an amazing game, and I for once can't wait for it to be finished.
Also, if you want you can compile it from source and play it, although it's not recommended as PonyKart is still quite buggy.
