The music aspect of the game has received overwhelmingly negative feedback, primarily due to its limited song selection and problematic monetization model, which locks most tracks behind a subscription paywall or temporary rentals. Players express frustration over significant synchronization issues between the music and notes, leading to a disjointed gameplay experience. While the nostalgic value of some classic o2jam songs is acknowledged, many feel that the overall execution fails to capture the essence of the original game, rendering it a disappointing and frustrating experience.
- “Very nostalgic music~!”
- “So nostalgic to play again some of my favorite songs and it's always fun to play them.”
- “I loved the music, and I still listen to the songs to this day.”
- “But on top of that, the selection of songs is complete nonsense with there only being like 20-30 songs in the entire game unless you pay a hefty subscription fee!”
- “The monthly subscription for access to all the songs is just greedy.”
- “Music and notes are not synced correctly, and to access all songs, you have to pay a monthly subscription.”

The gameplay has received mixed reviews, with many players expressing frustration over issues such as lag, poor note registration, and a lack of innovation compared to previous titles like o2jam. While some appreciate the core mechanics, they criticize the simplistic graphics, corporate feel, and mobile-centric design that detracts from the overall experience. Additionally, technical problems, including sound disruptions and incorrect image assets, further hinder the gameplay quality, leading to a general consensus that significant improvements are needed for it to be worth the investment.
- “I quite adore rhythm games of all different types, whether they have mania mechanics, you're clicking circles, spinning your mouse, or using visuals heavily to hit to the beat like Rhythm Heaven, Melatonin, etc.”
- “This game isn't entirely awful in regards to the gameplay because you'll at least hit great when hitting to the beat, but the charting is off and it makes it not entirely impossible to hit perfect, but exceptionally unlikely to do so.”
- “I would have been more willing to let this slide had it not interfered with the gameplay.”
- “I play for m2u songs because I love his music, but the game lags midway even though the gameplay is finished before the song reaches its end. There are bugs on songs not playing well, some glitches, and other technical issues.”
- “There's a lot that needs to improve gameplay-wise and graphically for it to reach a point where spending money on it makes sense. I feel like the best option would be for it to move to a permanent pack unlock/progression unlock-based model like the rest of the industry has already established.”
- “I would not recommend it now, and do not expect high-quality gameplay, as the game is still pretty much stuck in the late 2000s in terms of quality.”

The graphics of the game have received overwhelmingly negative feedback, with many users comparing them unfavorably to outdated mobile games and browser titles. Reviewers noted issues such as low resolution, pixelation, and a lack of polish, describing the visuals as simplistic and in need of significant improvement. While some appreciated the color balance, the overall consensus is that the graphics detract from the gameplay experience and require urgent updates to meet modern standards.
- “Nice game graphics though.”
- “Graphics being updated to a higher resolution (as some of the song backgrounds and note results look pretty baked).”
- “In-game 3D guitar-hero-like graphics.”
- “To start, the visuals look almost worse than a browser game. I played the old-school Beat2Jam/O2Jam v2 and v3 to palate cleanse after this tragic mess.”
- “The graphics look like a poorly made mobile game (because that's exactly where they were taken from). The charts aren't super fun from my experience, and the worst part: the song rental system.”
- “Song loading is eternal, charts are broken, UX is really poor, and the UI and graphics look like a +10 year old phone game at this point.”

The optimization of the game has been widely criticized, with users reporting severe performance issues, including stuttering, audio sync problems, and input lag, even on high-end systems. Many players describe the game as unoptimized and comparable to older titles that run more smoothly, leading to a frustrating experience. While some initial performance issues have been addressed, significant problems persist, making the game feel poorly ported and lacking in polish.
- “As for performance, the game stutters regularly and some animations even lag when I'm running the game with hardware light-years ahead of what's listed in the recommended requirements.”
- “Most of the complaints regarding performance and sync issues at launch are resolved, but there are still sudden network disconnections from time to time (thanks, GameGuard).”
- “It's not enough to make a huge difference to score, but I definitely had a few inputs drop due to lag, when a considerably heavier performance rhythm game, Project Diva Megamix, performs flawlessly on this system.”
- “Overall, this is a lazy and terrible port of a version of O2Jam clearly not optimized for PC.”
- “The game is stuttering most of the time, and it is not synced properly with the music and keys.”

The monetization model of the game has been widely criticized as a blatant cash grab, featuring excessive microtransactions and temporary unlocks that frustrate players. Many reviewers express disappointment that the game, which has nostalgic value, has been reduced to a soulless attempt to profit from its legacy, with a focus on monetization over quality gameplay. Overall, the monetization strategy is seen as exploitative, detracting from the experience and leaving players feeling cheated.
- “With regards to monetization, I understand that this is a free-to-play game with microtransactions, but they're terrible with 7-day and 30-day unlocks only, instead of permanent unlocks for your account from the original O2Jam for PC.”
- “I get it, you made the game free to play so that you can put in-game purchases.”
- “Tldr: it's a soulless nostalgia bait of a game that never improved since the early 2000s (and somehow downgraded) while incorporating the negative aspects of modern gaming monetization.”
- “Literally a freaking cash grab, old O2Jam mobile port to PC.”
- “Game became a cash grab, what an unfortunate end to a famous rhythm game from the past.”
- “All in all, a disgustingly bad attempt at a cash grab for people drowning in nostalgia.”

The overall sentiment suggests that the game lacks a meaningful progression system, making it feel pay-to-win rather than offering a balanced grinding experience.
- “Ranking rewards are only for the top 10, which means players who bought the one-month VIP pass will dominate in score farming.”
- “The grinding feels endless and repetitive, making it hard to stay engaged with the game.”
- “It often feels like the only way to progress is through tedious grinding, which can be incredibly frustrating.”
