Softlocked at the last puzzle piece area says I got one more piece to find used several guides all checked out.. I got nothing stuck at 55 and yes I did all side quests and bosses I think the piece that is hidden behind a wall is when it soft locked this area also stays purple and the breakable wall keeps returning after I leave the area return

For the final piece (Traitor in Our Midst), you unlock it when you beat Baal at the end of the game. You can get the side mission before you roll the credits.

@Twiig Oh,I didn't find the Kagero quest in the list and mistakenly believed that I cant find the boss after I beated the final boss.Now I get the last piece.Thank you very much

@hzq4621 That puzzle piece you get for defeating him was one of the last ones I picked up as well! I fought him after beating the game, I think I just needed to complete all other side quests for the quest to show up in the log but I can't remember for sure. Let me know if you figure it out!

I find I missed the Kagero Boss and finished the main story.Now I can't get the last puzzle piece.Is there any way to redeem?

@FritzWillie I unfortunately don't think you can to my knowledge, you'll have to grab the jet pack from the castle area (middle area) at the blue part at the top and bring it to that square to boost up...I pinned someone's comment that explained it in detail on my YT video, but some people can warp to it and some can't, we think it has to do with what squares you have left to find or something. Hope this helps

Hi, I'm having trouble with piece #43, the one at the top of a metal walled shaft where the HP up is on the left and the piece is on the right. It's the very last area on the map for me to discover, I've already beat Baal. I can't warp to the room like you did because it's still purple for me and says that Warp is temporarily disabled to this area.

When I warp to the point below that, my high jump doesn't get me near enough to the edge of either side to grab it. How do I change the location on the map from purple to normal so I can warp?

@SporkyReeve Hopefully you can snag that one and find the other one you are missing! The final boss is an awesome fight

@Twiig Thanks! I thought a jet pack might be the solution but I only remembered the one that's way far to the east. That's super helpful.

@SporkyReeve Thanks! These are not officially numbered in-game, they're just numbered in the order that I came across them! I have a pinned comment on my YouTube video that explains piece 43...apparently depending on which squares you haven't "found" yet determine which ones you can warp to after entering them. I was able to jump up, unlock the square, and then warp...but it seems a lot of people can't do that! A person in the comments said that you need to bring the jet pack from the central area to the western area of the map and boost up....they said it is located in the castle area (middle area) at the blue part at the top. The route requires a 32 chip door to be unlocked which should take you right to where the 43 piece is located. Let me know if you get it!
