This game was developed by Bonsai Entertainment and released by Natsume. Each of the levels consist of four main mini games, which the player can do in any order, and two final mini games that only appear at the end of the game. However, three of the main mini games are the same every level, with their only difference being a slightly increased difficulty level. The main goal of these games are to make it to the end with as much ooze as possible (ooze being fuel for the Lazarus and is much like points).
