On my blog I wrote a list of what I viewed to be best 2D platformers released on the Playstation 1.
Read it here
To summaries the top 5 were;
Klonoa, Heart of Darkness, Oddworld (1 & 2) & Castlevania: Symphony of The Night.

I've now managed to get a hold of every game in the list, and now I want to try and find more... So does anyone have any suggestions for other good 2D platformers released on the PlayStation?
As I can't seem to get enough of them

Cheers
