It's incredibly short. The environments are all very much alike. Pretty much no story. Characters don't speak and so aren't likable or interesting. Too much backtracking. Tedious repetitive combat system. It's a chore to keep fetching back the kidnapped girl. Same generic enemies throughout. A very annoying piston part that's supposed to throw you upwards but takes several attempts to do.
As I said the game came out the same time as FFX and there's absolutely no comparison in the quality of the two.
