The story in Quantum Protocol is generally considered simple and somewhat shallow, serving primarily as a vehicle for gameplay rather than a deep narrative experience. While the visual novel-style storytelling features charming characters and engaging dialogue, many players find the dialogue lacking and the overall plot underdeveloped. However, the game does offer enjoyable character interactions and a lighthearted tone, with the post-game content providing a more challenging and rewarding experience.
- “Quantum Protocol is a roguelite deckbuilding card game with additional puzzles to help understand the preliminary decks you have to work with throughout the story told with a visual novel approach.”

- “An excellent and creative twist on the card game with proactive and snappy gameplay, interesting storyline and characters, and gorgeous graphics.”
- “The entire story is a glorified tutorial that makes absolutely sure that you can demonstrate an understanding of all the game's moving pieces before it lets you go.”
- “The story is bare-bones and disjointed, told in dialogue only by a constantly growing cast of characters that’s honestly hard to keep track of.”
- “Considering the story’s weakness and the high gameplay to story ratio, I can’t recommend 'Quantum Protocol' to visual novel fans looking for a decent story with a bit of gameplay.”

Additionally, the sound design is considered a strong aspect, contributing to the game's engaging atmosphere.

- “Very fun and interesting take on the deck-building genre with, and I cannot stress this enough, one of the best soundtracks I've heard in a game.”

The game boasts high replayability due to its ascension system, unique deck strategies, and a postgame that transforms the experience into a roguelike environment with randomized elements. Players can revisit missions with different decks, and the final dungeon unlocks a mini roguelike mode with varied challenges and rewards. However, some users feel that the randomly generated dungeons may not be as engaging as the crafted ones, potentially affecting overall replay value.
- “The ascension system gives high replay value, and each deck has a unique strategy behind it.”
- “These components culminate into a very replayable game where many working parts harmonize and every part of its gameplay structure feels enjoyable and incredibly well thought out.”
- “Once the main campaign is done, there are also 5 levels of randomly generated 'ascensions' to give it the true roguelite finish for infinite replayability.”
- “After 30 hours, it is surprising to me how different the same level can be with each of Quantum Protocol's characters, which breeds the replayability required to succeed in the deckbuilding game archetype.”
- “My current early impression is that the random dungeons aren't as interesting as the constructed ones, and this may impact the game's replay value.”
- “This makes it so that the 'dungeon' levels, which are the main parts of the game, have added replayability due to the random nature of card drops, and the numerous deck types you can build using the various characters' card sets, or after progressing the game enough, potentially mixing archetypes from characters.”
