Spoilers ahead:
I can't do the Konami Code at the Blue Forest maze, since everytime I get to the "Down, down" part, it goes for another section of the map. Blinky says I had to bring Sunny with me, but that also didn't seem to work. Was that supposed to happen or am I missing something I had to do in order for it to work?
By the way, just noticed that, although I got all the 3 gems, there are only 2 of them in my inventory. I checked all of the 3 places and they were all picked up, so... I can't progress. Can I know/see what happens if you get them all and use them, at least?
1. you must also count the first screen for the code. Try following the fireflies. Sunny isn't needed to get there, but if you meet the witch and get a boob job, if Sunny is in the group learn how to do it too.
2. if you are referring to the three force stones, they are key items, unsalvageable and non-disposable, so if you found them, that means you have them. The first stone is where in the secret passage south to river ruins, where there are water lilies. Look at the bubbles in the water. The second piece is in snowpeak in the cave with the lava and the third in the temple, where you faced the golem. You need them to unlock the secret ending of the goddess.
I did get all three force stones, but only 2 of them remain in my inventory. Even before I sent this report, I checked the place for each stone and they were all taken, as I thought.
Blinky said I was missing 2 stones: the one at the lava area and the one in the water. I hadn't taken the lava one at the time, but I did take the one at the water in river ruins.
If you want, I can send screenshot of every place and my inventory, but I don't see a reason for such thing. Must be a bug that I'll just have to live with
