I'd caught the start of a blind playthrough by one of my favorite Twitch Retro streamers. Seeing the experience of someone new to the game (and the distraction of chat) spurred on the urge to replay it again. That said, there's a lot to delay progress or items to outright miss in the game. That could be by not talking to NPCs (and again as you clear an area), realizing what you can interact with, or revisiting some past areas.

My in game time was roughly 7h 40m. Oracle Stone said 98% complete. Full equipment and found / purchased every Life Stock outside of repeats in the final shop.

If you want my thoughts on the game, it's one of my favorites. The art and music is great (with strange sound effects). The platforming is overly complicated without being unfair - there's very little that's obtuse. Don't over think it. It's a rewarding adventure with plenty of little secrets.
