Always wanted to play this as a kid since I'm a huge Digimon fan, a ton of the games are on WonderSwan and in Japanese only. So I finally learned Japanese, and what this actually is is a cute, if basic monster raising game. A little repetitive and lost a lot of its mystery because I decided to eventually use a guide to figure out how evolutions worked (and from there it's a pretty linear route to whatever evo you want, I don't know why the gamefaqs guide made it out to be so confusing). Amazing sprite work, arguably the best Digimon has ever had in my opinion, though I do like the Digimon Story sprites for the most part. The story is a typical spirited away Digimon type story, but one cute detail is there is this meta aspect, when you start the game it frames that action as you stopping the deletion of this digital "Swan World", and in the game you are referred to as "the one who can input Digi-Codes". Kinda fun, especially since later one everything is just about "the" "Digital World" rather than this idea of pocket universes in every device. I actually didn't get to the end of this because I can't be fucked to build up a team of guys powerful enough to defeat Cherubimon even if the path to get there and min/max your team is not that hard (I watched some Japanese guy do it on Youtube, you can beat this whole game in 5 hours -- the two tricks you need are DNA digivolutions for power which you can guess with sufficient Digimon knowledge; and healers in the form of the Angemon line). In any case, felt really nice to solve the mystery of this game that has been kind of haunting me since my childhood, I can see this being a fun nostalgic time waster maybe.
