You should only really get Seal the Deal if you're a massive AHiT fan or really looking for more difficulty from the game. The chapter it adds is alright, but it doesn't really have the fun platforming of previous worlds and some of the missions are eh. Death Wish is a neat concept, but it does kinda get annoying to deal with whatever annoying difficult challenge the game forces you to go through - I do realize that this is just because I'm not that great at hard challenges though, so a masochist would love it.

DLC with amazing content, a really interesting stuff to already interesting levels, while also requiring more effort to get through.

Music is even better now, they added a lot of amazing tracks.

Reminder that the content is accessible because the devs added a mode if you die too much, that will make the death wish levels more forgiving. Which is great, I used it for some of them.

This DLC having mixed reviews is why we can't have nice things like an optional content adding extra difficulty and variety (or complete new levels!) to the base game.

A really great addition to the game that feels more heavily skewed towards the Deal part rather than the Seal part. Don't get me wrong, the new level is great, and I love the little seal fellas and how dumb they are, but a lot of the meat of this DLC comes from the Snatcher's challenges, which are actually very challenging! The game doesn't shame the player for not being up to the challenge, however, rather just providing a bit of levity when it comes to the challenge, with the catch being that it will say whether you used the easier mode or not. It allows skilled players to flex while letting people who don't want to spend all that time "getting gud" to just play the fun new challenges. All around a great time.

I see a lot of people trashing this DLC and praising the second one, but that is completely unfair. Nyakuza Metro is amazing but I honestly prefer this one. The 6th chapter isn't great, but it's clear that most of the effort went into the Death Wish. This DLC adds a lot of content to a slightly content light game.

The 6th Chapter is definitely the worst and shortest out of all 7 (aside from the 5th chapter for obvious reasons). However this doesn't mean it's 'bad'. The music is top notch as always however the level design is slightly off. I wish they tried a little bit harder with this chapter but that's okay. It's made up by the pizza time level that rivals that of spiderman 2 - music and all.

Death Wish is definitely not for everyone. It is brutally difficult and very similar to the Godmaster DLC from Hollow Knight in the sense that it reuses old content but with a fresh coat of pain. There is new stuff and the new stuff is amazing but most of the content comes from remixed existing levels. The content provided here is astonishing. It basically takes a game that's only 'flaw' was lack of content and it essentially doubles it. Snatcher's voice lines are infuriating but funny and well written. While I did say that the levels are incredibly difficult, the game does encourage you to buy an easier version of the level with in game currency. I will admit that I used this for 1 level because it was just way too difficult but it doesn't lock you out from any content or achievements. Some of the new music actually tops my favourites from the base game and that was a hard feat to accomplish.

The boss fights get their own paragraph because they are so amazing. I loved the base game bosses but I beat all of them first go (even with going into the game blind) and so having an actual challenge was a real treat. These are all really well made bosses as well, pretty much no random RNG crap that plague a lot of difficult bosses. The boss themes are definitely my favourite tracks in the game as well. They slap so hard.

In defence of many peoples complaints, I don't believe that death wish is unfairly challenging. Most of the levels are cleverly changed in a way that makes the level way harder, but still makes your death your fault rather than an unfair mechanic. I'll admit that giving a level a timer is just artificial difficulty but luckily only 2 or 3 levels have that. Also one singular boat themed level was just so hard that I had to use the easier mode to get past it (you know the one if you have played the game).

Also Rhythm Jump Studio is one of the coolest levels in the entire game.
