copper odyssey is a wonderful game with a lot of heart & soul put into it. the art is phenomenal and the sense of humor is so unique & funny. the music is great too and really fits the vibe of the game! it takes a bit to get used to the mechanics, but it's very satisfying to get good at and the game is thankfully very generous with second chances & chocolates (the revive and full heals of the game). the extra stuff like the costumes are really fun and i can tell there's a bunch of other secrets i missed too!
i like that mr woodcut can't be turned away from your party and is useless for the whole game.
PS i heard there's a very cool Secret Enemy you can find if you get the angel costume......
