Under Party, developed and published by SekaiFrieden, is a brutal, stylish, and unapologetically intense 2D action-platformer designed to test a player’s reflexes, patience, and tolerance for mature subject matter. Rather than easing players into its world, the game immediately establishes a grimy noir tone—urban decay, criminal networks, and underground torture chambers—and thrusts its protagonist, Aoi, into an escalating nightmare. What begins as a straightforward rescue mission quickly turns into a grim exploration of depravity, corruption, and violence. The story isn’t told through long cutscenes or elaborate exposition; instead, environmental imagery, enemy variety, and fragmented character interactions build an unsettling atmosphere that keeps players emotionally engaged even as they struggle to survive. It’s a game that refuses to dilute its thematic edge, and that clarity of identity becomes one of its defining strengths. Mechanically, Under Party is razor-focused on fast, punishing combat and tight movement. Aoi must navigate side-scrolling stages filled with heavily armed enemies, environmental hazards, and bosses designed to disrupt rhythm and punish sloppy execution. Instead of letting players brute-force their way through encounters, the game demands absolute precision—reading attack patterns, spacing correctly, dodging at the last possible moment, and countering with well-timed strikes. Even standard enemies can send Aoi flying across the screen, forcing players to treat every encounter seriously. This difficulty can initially feel unfair, but once the game’s logic becomes clear, each victory carries a genuine sense of accomplishment. That loop—failure, analysis, mastery, triumph—is the core emotional engine driving the experience. Level design complements that philosophy by emphasizing forward momentum rather than open-ended exploration. Stages are carefully structured, with escalating challenge curves and enemy placements meant to teach, punish, and ultimately empower. Many rooms function like combat puzzles, where survival depends on understanding enemy spacing, terrain limitations, and timing windows. Boss fights highlight the developer’s commitment to precision; they hit hard, require pattern memorization, and leave almost no room for improvisation. The game’s relatively short runtime becomes a virtue in this context—each segment is purposeful, with no filler or narrative padding. It respects the player’s time while still demanding intense focus and repetition. Visually, Under Party blends anime-inspired character art with grim industrial environments and stark lighting contrasts. The clean, sharp sprites juxtaposed against blood, grime, and rust create an unsettling aesthetic that reinforces the game’s thematic concerns. The animation is surprisingly expressive for an indie production—attacks feel weighty, movement is fluid, and combat feedback is immediate. The soundtrack supports the tension with dark electronic tracks and percussive beats, while sound effects lend impact to every successful strike or brutal defeat. Presentation doesn’t overshadow gameplay, but it successfully deepens the emotional tone, ensuring the player feels the violence rather than merely observing it. However, the game’s intensity also narrows its appeal. The one-hit knockback system and relentless enemy aggression may alienate players seeking a forgiving or exploratory action-platformer. Under Party is designed for those who enjoy friction—who relish dying repeatedly until a sequence finally clicks. Its mature themes, including explicit violence and disturbing imagery, are not window dressing but intentional narrative scaffolding. Players uncomfortable with darker content may find it overwhelming or gratuitous. Additionally, the linear structure and limited narrative depth may disappoint those expecting a more elaborate world or character arc. Replay value primarily stems from improving execution, not uncovering new story paths or secrets. Despite these potential barriers, Under Party succeeds because it understands its audience and commits wholeheartedly to its vision. It doesn’t chase universal appeal, nor does it compromise its tone for accessibility. Instead, it offers a concentrated dose of mechanical challenge, emotional tension, and aesthetic purpose. For players who enjoy high-difficulty action games, rhythm-based combat learning, and dark anime stylization, the experience is rewarding, memorable, and even cathartic. Each cleared room feels earned, each boss defeated becomes a personal victory, and the journey—not just the ending—delivers satisfaction. In the crowded indie action-platformer landscape, Under Party stands out not by reinventing the genre, but by embracing intensity with sincerity and stylistic conviction. It reminds players that difficulty can be meaningful, atmosphere can carry narrative weight, and small-scale games can provoke strong emotional responses. For those willing to endure its harshness, Under Party offers a challenging, uncompromising, and strangely compelling descent into darkness—one that lingers long after the final blow is struck. Rating: 8/10

I have 2 big problems with this game. First is parry. You press a skill button to parry. The thing is that you have to not press forward or back cause that would use the other move instead of parry. Which means that if I want to walk while parry, that's impossible. There are so many times where I just want to move forward while parry those bullets but I can't!! Second is that most of the enemy attacks are not react-able. How am I supposed to use parry then? I know I supposed to jump around or move to dodge attacks but c'mon man. You gave me an option to stay in front of all enemies and fight them that would be super cool. Other that those 2 big problems this game could be my new favorite game. Worth it on discount.

UnderParty really makes you feels like a Girl in a Ryona Film This game is brutal, challenging and down right unfair in some moments, having been made by literal sadists. The controls and Move-set are pretty fun while you get used to the mild jank. The art and CGs are nicely illustrated although fully clothed, as this game unfortunately doesn't feature any nudity, instead going all in on the Ryona part. Worth it on sale
