Hey, this looks familiar... Sigh. So, out of seven games, we have only five unique ideas. Same as puzzle 2 before it, you pop balloons and try to work around the grey "unbreakable" ones. I'm not sure how they got away with this a second time... I mean, if Quake 1 and 2 used the same maps, just different textures on the walls, you think Id would still be in business? Nope.
