Well, this game isn't what I expected it to be....
...that aside, it's really really good! Gives me early Pokémon games vibes. Equal times cute and creepy. Very enjoyable little game that has multiple endings and a few surprising plot twists. It's challenging enough to make your brains work but easy enough to find a satisfying solution.
...Although I have to admit I myself am stuck because I cannot find five more pebbles.
I wish it was square and had an option to have a greenish color palette to kick in my Gameboy nostalgia even more!
