during Ludum Dare 26 - the theme was 'minimalism' - I built Minimal Jump. You can play it at Scirra Arcade, or - if you'd like to vote - on Ludum Dare. The Arcade version has minimal (pun intended) bugfixes and a highscore list, though.
I'm already working on a bigger version, which will include several game modes and HD graphics (read: 8bit style).
Hope you like it. :)
