Todd and I (aka Gopherwood Studios) had a blast working on Heartbeat - Lightning Runners; check it out! Developed in collaboration with Digital Eskimo for the University of Western Sydney, this puzzle-platformer is aimed at addressing health and culture with aboriginal children in Sydney, Australia. It's built in HTML5, using Platypus and CreateJS for the game engine and rendering and Tiled for the level layout and design. Let us know what you think! (from our blog)
