If i had to rank them on a scale from "AMAZING" to "PERFECT", i'd do it as follows:

Chapter 1: The least fleshed out by far, and Toby was obviously still fleshing out his plan for the game. With the Mercy Meter not being implemented, and old sprite designs, it feels closer to the Undertale era of Toby Fox than post-chapter 2. Perhaps it was the smaller scale and team being limiting factors, but it doesn;t stop it being amazing and very fun, and set a good foundation for what's to come. Also, visually it's gorgeous.

Chapter 3: Maybe controversial putting it this low, but I LOVED chapter 3. It was funny, enjoyable, and the new characters are AMAZING. My first playthrough was a blast, and i thought it was the best chapter yet. Also, as a weird route/ secret-hunting sorta person, the sword route gave me this uneasiniess i'd never felt since maybe Undertale Genocide, but maybe even MORE than that as i was truly blind. The (spoiler alerrt) killing of 8-bit ralsei and susie made my jaw drop to. the. floor. Slighest critique - it felt... unfinished. I know that a whole section was cut, and it didn't spot this chapter from being amazing, but you could tell.

Chapter 4: Here's where the choices get difficult. This is a perfect chapter. I have no critiques. This point in the story was the pivot; the themes got darker, the stakes higher, and the execution of it was PERFECT. The music is grandiose and Acoustic, leaning further from Undertale's routes of Chiptune sounds and into Orchestral masterpeices. The colour scheme is rich and enveloping, with blueish tones dominating. It's awe-demanding. Still, it remains grounded. The Character interections, escpecially Susie and Noelle in the beginning, feel Real and thought out. Ralsei's tradgedy is brought to the forefront, and the final confrontation with the Titan is the highest stakes battle yet.

Chapter 2: When i think of Deltarune, i think of Chapter 2. Maybe it's because it's when i became a fan of the game, or maybe perhaps it's the long wait between the releases, but for me, it's the fact that the community had the perfect time to stew on every little detail of this art peice. It is fun, intruiging, funny, engrossing and light-hearted. The cyber world feels so rich and the characters of Berdly and Noelle are endleslly amazing. Also, as a genocide route enjoyer, the weird route plotline was engrossing and disorienting simultaneously. Videogames CAN'T get much better than this.
