I'm super mixed on the dlc. It introduces a brand new chapter and an entirely new difficulty option (Death Wish) with remixed levels. The new chapter Arctic Cruise is probably the weakest chapter in the game since it only has 3 main levels and I hate level 2. But overall, it's still fun. However I did not like most Death Wish mode. It takes a bunch of levels in the game and remixes them to be 100 times harder and most of them were incredibly frustrating. I probably put about 50 hours into completing this mode and I really enjoyed about 10 of those hours. The remixed boss fights were a huge highlight and were a ton of fun to learn and master. But most of the other levels felt poorly designed and frustrating. I did go for 100% and managed to do it but I don't recommend anyone doing it. Not fun but Arctic cruise and the remixed bosses make the package a little better.
