What a charming and unique game! I love the papercraft style and the gameplay is also quite smooth when you get used to the controls. I like how the gallery saves your photos too, even if it only comes into play for the Aya quest. Unlike other folks here, I was able to figure it out immediately. The quest I had a little bit of trouble with was the Byakuren quest, I thought the answer was by going through a long platforming section for the iron maiden thingy but turns out it was the hat all along... The story is simple but sweet, hehe
The photography mechanic was really well done and even though it was used for the Aya and Remi/Flan quest, I wish it could've played more of a role and/or caused some interesting reactions. Like taking a photo of the fish and showing it to Aya, or taking a photo of the Cirno prism to get special dialogue (lmao), etc.
I really enjoyed this game overall, good work!
