I have found 268 items, all of the items in all 1s through 8s, plus both Light & Dark Overworlds. Not I'm not sure what to do next. I have found all level 9's but no triforce pieces. I discovered the purple warp at the beginning of the overworld using the Lens but not sure how to activate it. I've been on every screen ten times over. If it matters, I'm using the preset item locations instead of the randomized locations.
Thanks!
