A sub-90-minute beat-em-up that plays like a vault door was welded shut in 1989 and someone just found the key. Hard pass for casual brawler fans; maybe a curiosity for Kunio diehards.

I came to this one expecting the kind of no-nonsense, pick-up-and-punch loop that makes a short brawler worth keeping on the drive. What I got instead was a game that feels genuinely frozen in time, and not always in the good retro way. Stay Cool, Kobayashi-san is a side-scrolling beat-em-up built around Masao Kobayashi, the Reiho High rival from the original River City Ransom, now dragged into a time-travel plot involving a future regulator named Mizoguchi and an evil organization sending color-coded goons to disrupt the space-time continuum. The premise is gonzo. The execution is mostly middling. On paper, the character roster has promise. You can field Kobayashi, Mizoguchi, Kunio, or the Dragon Twins, and each carries a distinct move set. Kobayashi gets three normal attack chains plus two finishers; Kunio has his own combos and three finishers; the Dragon Twins and Mizoguchi each slot in with their own rhythms. Special moves run off a Spirit Meter, chargeable to three levels (blue, green, red), and there is a double-jump that lets you extend aerial pressure. On paper, that is a decent toolkit. In practice, the combat feels stiff right up until you dig into the hidden directional inputs, and even then the feedback loop drains fast because the enemy pool is tiny. You are mostly fighting color-swapped masked soldiers, beam-sword orange grunts, projectile-spitting purple and red variants, and UFO drones. Repetition sets in hard before the first run is over. The structure is where things really fall apart for a solo player. The game wants you to roam a small open map, find the right gang color in the right zone, hit a quota of 30 defeated members per color group to unlock one of the five bosses, then repeat for the next. There are no zone indicators, no mini-map markers, no shop progression or stat-eating food that the main Kunio-kun series is known for. Stars earned in combat let you power up characters, but it is a thin substitute for the RPG layer that made the original River City Ransom memorable. You can earn a permanent power-up on subsequent Kunio runs by triggering a specific story beat, which is a nice hidden touch, but it does not fix the aimless backtracking that dominates most of your time. The real kicker is the Kobayashi-must-live rule. If AI-controlled Kobayashi walks off a ledge while you are playing as anyone else, the run is over. AI partners are not reliable enough to make this feel fair. Local co-op genuinely smooths out a lot of the friction. With a second player managing Kobayashi, the zone-clearing loop becomes a short, breezy session, and the multiple-ending system (20-plus endings tied to which boss order you clear) gives the duo some reason to replay. The 16-bit visual upgrade over the older Kunio pixel style looks clean, the animations are lively, and the dynamic soundtrack that shifts theme depending on which character is active is a small but clever detail. The voice acting is wall-to-wall, which some players will find charming and others will mute inside ten minutes. Translation quality is rough enough that story context is mostly lost. Solo, the whole thing clocks under 90 minutes and the Steam community consensus lands at mixed, with just over 40 percent positive reviews. That number tells the story. Fred, Scout Team

GamerScout Verdict

Skip solo unless you are a Kunio completionist; a second couch player turns this from a chore into a passable 90-minute throwback.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
