Edit: Since I figured it out the below shortly after posting, we can help each other find missing stuff in general here! I've played through the game 5 times to the end choosing different paths, and explored some chapters a second time. By now I've visited every island and have found every sticker for the almanac, but one. In Trade, Gifts & Things found page 2/2 there's a missing triangular shape next to the Njarfoot charm. Where should I look?! Has anybody found the right island?...

I tried to play the game on my laptop but there seem to be a lot of graphic problems which make it unplayable to me: https://drive.google.com/drive/folders/1NKl8RhV_l_-4wILlgSi1UWqVAyMF9UWt?usp=sharing

SPOILERS --------------------------------------- finally played through the game. i really loved stew, her family, her loving husband and her wonderful island full of cats. i missed five different islands to explore, im not if i was able to save stew. is there a different ending to save her? i felt so bad for her daughter : (...

Stew passed away on the island of the Sky Eye, but later a dialogue between Iris and her still triggered on board; specifically the issue resolution conversation about Iris and Stew's reconciliation.

I really enjoy playing spoils but some of the matches can be ridiculously hard to win. Like on Malton I tried many times to beat the cheating kids but I thought maybe there was a chance to win. The same goes for the chapter 10 Grace level. Are those games a guaranteed loss? Also on Fort Alcazar the requirements for that challenge are extremely hard to satisfy. I replayed it at least 8 times and my efforts to have a loss no greater than 48 points or whatever was actually very difficult to achieve....
