Year: 2025
I have made many posts this year mentioning my love for Toby Fox’s Deltarune. As a huge UnderTale fan of nearly 10 years, I was thrilled when Deltarune was announced back in 2018 and I have been watching its development closely through the UT/DR seasonal newsletters. The launch of Chapters 3 and 4 in early June felt like a long time coming, and I’m thrilled that they’re now out in the world for everyone to enjoy (and make theories about!)
As chapter 3 and 4 are newly released, I’m going to be writing a review of them on their own, separated from the demo chapters 1 and 2. Maybe one day I’ll be writing a review of the full game!
Warning: Spoilers ahead!
What I liked:
Chapter 3 and 4 start to shift the tone from the earlier chapters silliness into more endgame territory, with more detailed looks at the prophecy and what it means for our heroes. I think that chapter 3 in particular acts as the perfect segue into this more serious and dark tone, balancing fun moments and whacky characters in the minigame segments with detailed looks at our protagonist, Kris’s past. Everyone knew that chapter 2 in particular was going to be difficult to follow in terms of iconic and funny moments, but I think chapter 3 blended the funny with more character driven serious moments in order to mesh well with the darker tone of chapter 4 afterwards.
Chapter 4 was gorgeous through and through. The level design, the music, the enemies, the character moments were all beautiful and really made me want to see what chapter 5 has in store. Luckily we don’t have to wait long as it’s coming next year! The more serious tone of chapter 4 allowed us to see the protagonists in a whole new light, making them feel more real than ever before and I adored every moment. I especially loved seeing Susie’s development in this chapter; she felt like a true hero.

It comes as no surprise to anyone but as mentioned briefly, the music in this chapter slaps as always. Every chapter continues to have a distinct feel while all coming from the same game; the aesthetics of a medieval castle to a cyberpunk city to an old-timey TV set. I often listen to a playlist of all UnderTale and Deltarune music while I work or chill out at home, and while each chapter has a distinct feel, they all blend seamlessly together even when I’m listening on shuffle. I particularly love the Sanctuary and Guardian boss music from chapter 4, and the TV world and Tenna boss music from chapter 3.
What I didn’t like:
I went in to Deltarune chapter 3 and 4 incredibly blind; I was playing them less than an hour after it launched. I had a good go at figuring out how to unlock the chapter 3 “secret” boss (not really secret, but IYKYK). Turns out there’s so many points where this side quest can be aborted by mistake, to the point where it’s frustrating to have to go back and do the main quest again in order to keep the side quest going.
I also would have liked the second board in chapter 3 to be a different game from the island exploration one that we played before, especially as the game show takes up a large portion of the chapter. It would have been nice to get a bit more variety!
Closing thoughts:
I’m super excited for the next instalments of Deltarune! These chapters have really set up the game for a phenomenal final act. While the tone is more serious, we’re still getting a fair share of fun and light-hearted moments to enjoy.
Rating: 10/10
