Immediate oldschool vibes, MOTHER/Earthbound, SNES-era, which I adore. Kudos on the art style right there, for starters. The music almost fits what's happening, though for a mellow walking moment it's a little too excited, perhaps.
As far as the dialogue goes, since in this type of game telling a story is really important...none of it is really compelling at all, and the translation is...not...great. That's not a knock on you at all, for the record. I only speak one language, so I'm not one to talk...but for the sake of honest feedback I have to say: get a friend, a stranger online, someone, and pass them the writing for a one-over before using it in a narrative experience. It's just too important not to.
Only other feedback I have is I could not tell if I'd reached the end of the game. I talked to the octo-thingy, travelled the spike path, and then boop, returned to the main menu. I tried this several times assuming I might be missing something, but I found no indication.
Overall a really cute, if not too short experience which would have benefited greatly from leaning hard on the story-telling side. These graphics coupled with a great story could be an underground success. Keep at it, thanks for giving us a game to play!
