I help people make games. On my new site ("Red Blob Games") I post interactive tutorials and guides to game algorithms. On my previous site (Amit's Game Programming Information) I collect links to useful pages about maps, grids, tiles, pathfinding, and AI. On my blog ("Blobs in Games") I post experiments and projects and ideas. Previously I was an advisor to Wild Shadow Studios (Realm of the Mad God) and Root 1 (educational games).
