Nice and relaxing, I like it.
The only problem I had was finding where my photos went, it took a wile to undestand that playing with the itch.io sandbox active prevented the game from saving the photos on my pc.
I don't know if you'll have the same success with this, but with the sandbox enabled I was able to find the saved photos in::
C:\Users\itch-player-[your-unique-sandbox-ID-here]\AppData\LocalLow\Jannik Boysen\Shutter Stroll\Photos
Thanks, that did help indeed :-)
