I loved it!
cute art style with crisp line art and pastel colours, the game's main mechanic of trying to get the right sound was fun to mess around as all the sounds were pleasant to the ears. The game's world was pretty interesting with the marks left behind by what I assume to be people who were here before the player character, I'm also curious to see what's to the east of the playable section of the island.
English localization was pretty good, though I think the message on swapping items should be changed from:
"Replace [new item] with [current item]"
to:
"Replace [current item] with [new item]"
just for grammar, its not a big deal ^^
I'll be sure to buy the extra content soon too.
