Cassette Beasts. Man what a game, it's like Pokémon but everything's better. I almost can't believe that's an indie game (it's not perfect obv, but still)
I loved this game when I was 5-6 years old. I actually forgot about it now that I'm in my 20s but when GOG made that giveaway I immediately downloaded it. It's still fun
Mussolinette is a great name lol
