Can't get enough Klonoa!!!! I keep flip-flopping between the first and second. I find the first (Door to Phantomile) is more challenging in a raw platforming way while 2 (Lunatea's Veil) is designed in a much more strategic way that makes the player feel like they are solving small puzzles as they platform.

and then there's this wild Japan-only PS1 game that I've recently become obsessed with called b.l.u.e. Legend of Water it's an exploration game not entirely unlike Tomb Raider but the swimming mechanics are unlike anything I've played and I'm sure unlike anything at the time. Although I can't make it far into the game because I don't read Japanese and can't figure out how to save my progress. Gameplay and basic story is easy enough without knowing the the language tho.
