A one-button bullet-heaven that stays calm, even when the screen turns into neon chaos
Reviewed on PC.Score: 8.5/10
After just under two hours with THE KULKA, I walked away surprised by how relaxing it can feel — even when the game is clearly trying to push your reactions. This is a one-button arcade roguelite that blends that “one more run” pace with a clean, colorful presentation, and a soundtrack that keeps the vibe steady when things start accelerating.

What THE KULKA is trying to be
The dev describes it as a one-button bullet-heaven arcade roguelite — basically Flappy Bird colliding with Vampire Survivors. You tap to keep your orb alive, your shot fires automatically, and you level up into increasingly wild bullet mutations. The simple control idea is the hook — the real “game” becomes positioning, timing, and survival once the screen starts filling up.
The feature set is built around fast restarts, leaderboards, challenge/progression unlocks, and multiple difficulty presets — including Relax for chill sessions and tougher modes for sweaty score chasing. There’s also a second upgrade style called Flow mode, which uses automatic upgrade choices so you can focus purely on dodging.

My first impressions after ~2 hours
I played on the Relax difficulty, and that choice absolutely shaped the vibe. Even when the pace picks up, the game’s ambient music keeps your stress level down — it’s the weird kind of calm where you know you’re in trouble, but the soundtrack refuses to let you panic.

THE KULKA language menu shows lots of available options.
Controls are exactly what you want from a one-button game: Space or left mouse, and you’re good. Up-down-up-down. The clarity is a big win here — you understand what’s happening quickly, the loop is easy to learn, and the “just one more run” pull shows up fast.
But “Relax” doesn’t mean “free win.” Early on, you get that feeling of “I’ve got this,” then the speed ramps, enemy patterns tighten, and once you push into higher levels, the run can collapse fast if you lose rhythm.

Settings overview: Ultra graphics, Relax difficulty, and Synthwave background grid options.
I also want to highlight optimization: on my setup (49-inch super ultrawide), it runs well — but it’s not really a game that needs 32:9. This feels like it would be perfect on a tablet or mobile-style session, and Steam support for Remote Play on phone/tablet makes that idea even more tempting.
Difficulty + Flow mode (auto upgrades) are next for me
I still need more time with Easy / Normal / Hardcore to see how much the feel changes when the game stops being chill and starts demanding perfection. I also want to test Flow mode (auto upgrades) properly — because that’s the kind of setting that can turn this into a pure dodge-and-survive arcade fix.
Release timing + wishlist call
THE KULKA is not released yet — it’s scheduled to unlock on December 23, 2025. If you like neon arcade roguelites with quick runs, this is the moment to wishlist and follow on Steam.
First impressions score
Score (first impressions, ~2 hours / Relax difficulty): 8.5/10
This is based on early time with the game and one difficulty preset — I’ll revisit the score if the higher difficulties (and Flow mode) shift the experience in a major way.
