Hedgehogs is a free 2D physics puzzle game targetted at the casual gamer. Your goal is to figure out how to use the blocks and their physics to roll the hedgehogs to the inflated frogs and make the hedgehogs' stings blow the frogs up. Although this is a complete game with 21 levels, intro and outro and funny sounds and animations, it is meant to be a prototype for a much more complex game. If people like this version, I will create a much bigger version with at least 60 levels and many new and unique elements like fans, hanging bridges, ropes and platforms, water, Now, have fun with the Hedghehogs.
