Now I know this is a long shot, but I have some fond (if incredibly vague) memories of two games that were installed on two different Macs my family had. One was a 3D platformer where you played as a bug (and was most definitely not A Bug's Life) post 2000, pre-installed on a Mac desktop and the final boss was a red fire-breathing ant. The other was a 3D platformer where I think the first level had the player character saving farmers from being abducted by aliens, post 2000, pre-installed on a MacBook.
Has anyone here ever heard of either of these? Because I'd love to rediscover them.
