If you don't already have Shovel Knight: Treasure Trove you should probably just get that since it contains this amazing game with 3 other great campaigns included too (and a platform fighter).

Shovel Knight: Specter of Torment is my favorite platformer of all time. Its such an amazing game to play, everything in it is so well made. All the levels are very fun to go through, the soundtrack is a bop, the story is genuinely great, and theres even more great things with this game im not including, like how you can use your scythe as a SKATEBOARD!!!

10/10 video game please check this game out
