An offbeat Sega Technical Institute puzzle-maze game, about average in the US and far dearer in its Japanese form.
The Ooze was developed by Sega Technical Institute and published by Sega. It came out in North America in September 1995, in Japan on 22 September 1995 and in Europe on 2 February 1996. You play a slimy puddle of liquid, the transformed Dr. Caine, spreading through mazes and solving puzzles. Game Players described it as an exploration game whose success depends on puzzle-solving and conquering intricate mazes. Sega's marketing department considered bundling it with the Genesis Nomad, but that did not happen.
Opinion was mixed. One critic found the graphics dull yet thought the game worthwhile, calling it a quietly original, unassuming little game that you end up playing more than you intended.

“Most importantly, The Ooze isnot even-fun to play. It seems more like work than a game. If this is the last frontier of 16-Bit, | bid thee farewell.”
Undated scores are from the review table in the game's Wikipedia article, limited to reviews of the Genesis version.
Before you buy
Among US carts it sits above the middle, and the risk tier is Medium, so ask for a photo of the board before paying for a complete copy. The European cart usually costs much more than the US one, and the Japanese cart usually costs far more again; its cartridge has a different shape that needs an adapter or the removal of two plastic tabs in a Western console's slot.
