-Managed to find all 10 shells!
-Liked the most how there's different kinds of puzzles challenges for the different shells that feel natural.
-Disliked the most how there's several "blank" glowing spots with no shells, I'm pretty sure there's some rule that in game making that if something's shining then there's gotta be something useful in there.
-Yeah, I could see this style of gameplay extended into a bigger game, some super shell collector traveling to different locations facing new shell finding challenges.
