Having owned this game before on disc, It is very much one of these hidden gems, while it might look childish its honestly up there for me with the likes of tomb raider 2013. Eidos had some very great talented studios workin for em back in the day.
To speak a bit about the game then its a cool cartoony action adventure game with ninjas. Each level is a little open world in its own and with a very cool art style (IMHO) that still holds up. Runs on basicly anything, costs nothing these days. Defo reccomend. 8/10

Played this game when I was like 6 it still holds up

its a bit old but overall a good game. reminds me of Zelda BOTW
