Both Klonoa games include a few fantastic tracks, but not every song is quite up to that standard, and a few are fairly forgettable, if not downright annoying.
The Klonoa: Door to Phantomile remaster can look a bit flat at times, which is less than ideal for a game which deals in 3D space the way that it does. Klonoa 2: Lunatea's Veil holds up much better, however, with detailed and imaginative levels that have translated really well from the PS2 onto modern consoles.
Both Klonoa games have great level design, full of hidden collectibles, multiple paths, and fun platforming puzzles to work out. Klonoa himself can be a tiny bit slippery at times, but for the most part, he handles really well.
Klonoa Phantasy Reverie Series brings both titles up to date with some good quality of life changes, including the new easy difficulty mode. The lack of options when progressing text or mixing different difficulty settings are notable in their absence, however, and there’s very little additional content outside of a pixel filter, which only really works well with the first game.
This is a nice and easy list, if a bit simple. It won’t take you long to unlock everything, but you won’t be asked to do anything interesting or unusual either.
