The game features charming anime-inspired art, expressive character sprites, and high-quality CG illustrations that appeal especially to fans of the Null & Peta franchise.
Voice acting and soundtrack effectively capture the playful yet occasionally emotional tone of the story, enhancing narrative segments and character interactions.
Accessible and straightforward side-scrolling gameplay provides a lighthearted, casual action experience with some exploration and unlockable abilities.

Gameplay is regarded as clunky, repetitive, and lacking depth, with awkward controls, uneven key mapping, and some frustrating enemy placement or difficulty spikes.
The story heavily relies on prior knowledge of the Null & Peta anime, making it less engaging or confusing for players unfamiliar with the franchise.
Technical and design issues such as oversized text font overflowing dialogue boxes, absence of a map for navigation, and occasional bugs detract from the overall experience.

The gameplay is a straightforward, traditional side-scrolling action experience that is generally accessible but lacks innovation and polish, with some clunky mechanics and limited depth. While fans of the source material may find it engaging, newcomers might be deterred by its simplicity and occasional immersion-breaking flaws. Recent updates have slightly improved gameplay variety, but overall it remains average and unremarkable.
- “While the mechanics do not attempt to reinvent the genre, they provide a consistent action loop that is easy to grasp.”
- “It delivers a colorful and energetic experience that captures the charm of its source material while providing accessible, if somewhat straightforward, gameplay.”
- “Although many of the game mechanics are clumsily implemented, it is at least good that the developers showed some improvements by adding stages that take more advantage of the equipment mechanic and the unique characteristics of weapons, such as introducing invisible enemies or breakable rocks in the recent update.”
- “The movement and clunky design, not to mention the basic gameplay, make this game almost unplayable.”
- “This explains the trivial difficulty and abysmal quality of gameplay.”
- “The difference between weapons may not be immediately obvious, but it lies in the range and the time it takes to use them during which you are vulnerable to enemy attacks, which might be a source of annoyance rather than an element of gameplay to some people.”

The story of Null & Peta: Invasion of the Queen Bug serves as a continuation of the anime, focusing on the inventor Null and her android sister Peta battling a digital threat. While praised for expressive character art and voice acting, it heavily relies on prior knowledge of the franchise, making it less engaging for newcomers. Some reviewers found the narrative simplistic or lacking depth, though fans appreciated its emotional beats and lore expansion.
- “At its core, the story centers on the genius inventor Null and her android creation Peta as they confront a digital menace known as the Queen Bug, a corrupting force threatening their world.”
- “Character sprites are expressive and lively, and the event CG illustrations offer high-quality artwork that expands on the story’s emotional beats.”
- “I think that the story could have been made better by explaining who Kaki (the beach girl in episode 6) was or what had happened to Null and Peta's parents who are mysteriously absent both in the game and the anime, which would certainly have enhanced the emotional side of the story, though I am content to see the origin of the bugs explained and learn more about Null and Peta's sisters.”
- “Additionally, those unfamiliar with the null & peta universe might not fully appreciate the story elements, as much of the emotional impact relies on pre-existing attachment to the characters.”
- “Story-wise, null & peta -invasion of the queen bug- is rather dull.”
- “There is no real story available here but the player just goes through event cutscenes when they arrive at a special place or make progress in a stage.”

The music is generally upbeat and electronic, fitting the cybernetic, action-focused atmosphere with clear combat sound effects. While some players find the soundtrack engaging and well-suited, others criticize it as repetitive and bland, indicating mixed reception overall.
- “Sound effects for combat are crisp and clear, and the soundtrack leans into upbeat, electronic themes that match the cybernetic setting.”
- “Great soundtracks.”
- “Plain, bland, boring, repetitive music. This sounds like a newbie programmer trying to make an action game for the first time; even other indie game developers do better.”

- “You're gonna hear that 'nuruuu' again from the familiar voice actor, and look at some nicely drawn art while upbeat music plays in the background.”
