^ You don't need ALL the lightseeds to open up new levels. You "only" need 540 (I believe that's the correct number) to beat the game.
Early stages deffo the one am on I need them all, I've tried but I simply can't find my way to some of them. Its still a cheap way to extend the gameplay I mean 540
Heh, yeah, I gave up about 5 hours into the game due to those damn lightseeds. Forcing the player to backtrack through each and every level immediately after beating it with nothing changed except for the graphics? Worst idea since Bomberman Zero.
At least Sands of Time was awesome.
