This is one of those games where I feel what you get out of it is very dependent on how much you resonate with the game's message. And for me, I very much resonate with it. I was not expecting to be hit by feels and spend a solid chunk of time just... reflecting on our little Pebble's "adventure".
Honestly, I don't even know what sort of feedback I can give for this one...
However, I will say that Biboo's words of never giving up, and how she hopes to inspire others to be that way as well... I think that is very much reflected here. For that, alone, I'm thankful to have played this game.
Well done.
Edit: As I finished writing this comment, I looked back at the game at the... let's just say "positive 15 minute mark" and saw that all the platforms disappeared. Looks funny to see pebbles and Biboo just floating in the air now. They came back at about the 17 minute mark though. I think it has something to do with the platform assets not loading properly during a specific season change.
I don't think anyone else would keep their game running that long or if it really impacts anything by this point or if this is even a replicable bug but... figured I'd bring it up after seeing it just in case.
