Such an imaginative concept that's explored so well. A lot of variety in the gameplay, with radically different scenarios and many powers and types of movements you can use. Hilarious dialogue, charming characters, so much attention to detail (every NPC has dozens and sometimes hundreds of responses and the artistry of some of the locations is astonishing), and lots of collectibles which you are well rewarded for. Clearly made with a lot of love, and you'll fall in love with it too.
Runs well even on an old PC. There are a few moments where the platforming can get tricky, but the whole game can be done even on a keyboard. Even if you don't care for platformers, make an exception for this one, because this game gives you so much.
