Had access to the Ch 1 'Tracks in the snow' demo, via Steam: thank you.
Cute concept and I like the simple artwork very much. I also like the more inclusive (though wholly inclusive would be difficult) sibling pair and that Bo looks trans/gender fluid (is that intentional?). I like the anime look of the characters, which seems unusual in a US-produced (I assume from the truck number plate) game.
I agree with other commentators that possible interactions with objects are basic, but I wouldn't mind this in future chapters provided that the mysteries are interesting and (as implied by the preview list) more challenging.
Enjoyed it as a British older adult who plays mostly mouse + keyboard indie 'casual', 'adventure', 'narrative/story-rich' and 'puzzle' games - and franchise HOGs when I'm tired - and I can think of under-10s who'd like it too. I might get bored if future chapters remain easy for me.
I noticed a few typos:
One of the Insight cards says "Foresincs showed" instead of "Forensics showed"
Near the end, Bo says "Dad, I'm right, don't I?" instead of, for example, "Dad, I'm right, aren't I?".
I'm looking forward to the release of the full version.
