The followup to the first game. Plays very similar to the first game and offers more levels. The big innovation in this one is that Gubble now needs to walk to tools instead of hovering over enemies. According to Wikipedia: "From 2000, the game was fully playable online at PlayMachine.net, using pay-per-play tokens (PlayMachine.net was an attempt to bring game arcades online)." The game also came with a level editor called ZymEdit and the Gubble Fan Club. It's not sold by the developer anymore but you can probably find it on your favorite abandonware site.
