Neat premise and cool artwork. I like the idea of the hidden object detective game, but the first level might need to be a bit more obvious for onboarding players like me.
I got stuck after the bench, so I tried switching to different cases, as instructed, but they didn't appear to be available until I finished the first picture. I'm not sure how linear your story is, but if it's possible, maybe let players work on multiple cases, so they don't feel blocked?
Feels weird to have to go to the walkthrough cheats straight away.
Still, great effort. Player onboarding is hard, especially with the wide disparity between lazy players and dedicated players.
