Ok, time for some serious critisizm!
Visuals:
Can't describe how beautiful it is. Just pure masterpiece!
It really has a lot of calming atmosphere in it and you just feel like exploring the world (seriously, you could just make a huge map without any interactions and I would just spend hours exploring it :P)
If I were to advise something, maybe it would be about consistency of art. For instance stars we are collecting are much different from the one that is shown in the UI, so it confuses a bit (it's good to stick to 1 version as message can be a bit unclear). Also I kind of felt like the button was a bit too out of this underwater world (hmm maybe if it was blue?). But apart from that masterpiece! I wish you win the graphical part of the competition.
Gameplay:
Very smooth and adorable, it was a pleasure to move around, bounce of those cute animals and probably nothing to add here. I just wish the game was longer so that I can dive into it for much longer time.
Audio:
Oh, that's one of the best game jam soundtracks I've ever heard, just wonderful job! I'm listening to it all the time now :P
It's so well fitting, beautifully made and just perfect.
If you could make the transitions between music fluent, it would be just so wonderful. While scenes were changed you could get taken away from the climate for a bit, because of sudden music change.
Game Design:
I love that very delicate story and how nicely it's presented in gameplay and art. Really makes it a whole! World is interesting enough to just wander around and enjoy your time :)
Overall:
One of the best games I've played in a last time, just made my mood much calmer :) Thank you!
