As far as I can tell, it's a licence based on a live action adaptation of a book series from the 90's of the same name, Animorphs: Shattered Reality. I have never hard of the book series or the show, so I can't comment, but when something isn't remembered from the same era targeting a similar demographic as Power Rangers or Goosebumps that's got to be a bad sign. @kingpotatoThis is what is referred to as a 2 1/2D platformer. Mostly 2D, but with a third dimension being explored in some aspects of the gameplay. Crash Bandicoot works in the same genre.
This is a let's play I found being played by someone who is familiar with the source material, so it's a good insight into what the game is about. As aforementioned, it' a 2 1/2D platformer with some bizarrely brief combat sections where you morph in an animal (That's something from the lore I assume). It looks clunky and difficult to control, it's not a particularly good-looking game with odd on odd mix of at styles and low res' graphics even by PS1 standards, although it looks challenging and there's a varied offering of platforming obstacles. Overall, I doubt it's worth playing, but @The Blackangel, I'll let you judge for yourself.
