Humpty's Scramble (1998)

This game was made to promote the western-Canadian family restaurant chain "Humpty's" and their Kids' Club. In this 1998 DOS platformer, Humpty must rescue his little buddy Hammlet from an evil wizard by traversing various areas including a forest, a marine cave, a mountain, and a maze-like castle. The game was sold and distributed for free at certain locations. Despite having a rather limited release, it impressively touted pre-rendered 3D visuals and a first-person 3d maze in its final area.
