Ball x Pit is the game nobody expected to obsess over in 2025, yet here we are. A ball-bouncing roguelite that somehow fused Arkanoid mechanics with city-building simulation, published by Devolver Digital, arrived in October and sold 300,000 copies in five days. Behind this chaos is Kenny Sun, a solo developer from Brooklyn who spent years iterating on a deceptively simple concept: what if you took the free-to-play mobile breakout game Punball, removed all the predatory mechanics, and made it actually good?
From Mobile Frustration to Desktop Masterpiece
The origin story is perfectly indie. Around November 2021, Kenny Sun discovered Punball, a mobile brick-breaker roguelite that immediately hooked him. The gameplay loop was addictive, but the free-to-play monetization was crushing. Energy systems, battle passes, aggressive IAP. All the usual mobile game garbage that turns fun games into time-gate simulators.
“I got hooked but didn’t like all the free-to-play elements,” Sun explained to IGN. “So I wanted to make a version without that — a buy-once experience.” That simple idea became Ball x Pit. What started as a straightforward cleanup of a mobile game gradually evolved through years of iteration into something completely different. A roguelite disguised as a simple ball game hiding a complex city-builder that ties everything together.
The Accidental City Builder
Ball x Pit’s genius is that the city-building doesn’t feel forced. After completing a run in the pit (successfully or catastrophically), you return to the surface where you build and manage a small town. Collect wood, stone, and gold from runs, assign workers to gather resources or advance construction, and gradually unlock permanent improvements to your character’s starting arsenal.
This meta-progression transforms what could have been a repetitive arcade experience into something endlessly compulsive. Early runs might feel limited and weak. But as you unlock buildings that improve starting stats, grant new characters, or unlock special abilities, each subsequent run feels progressively more powerful. The city isn’t just a menu system. It’s the reason you want to run the pit again.
“I wanted something more visual and personal than just menus,” Sun explained when asked why he implemented the base-building. “Something with identity. I liked the idea of little characters bouncing around a base. Plus, I did base-building in my last game, so it wasn’t a huge leap.” What sounds like a practical decision became the core pillar of the entire experience.
The Roguelike Blend That Shouldn’t Work
Ball x Pit combines genres that logically shouldn’t work together. Arkanoid-style brick breaking. Roguelike progression and item combinations. Vampire Survivors-style screen-filling chaos. City-building management. That’s four completely different game types mashed into one experience. Somehow it all clicks.
The combat feels like precision-engineered flow state. You aim balls directly at enemy hordes that slowly descend the screen. Defeating enemies drops gems that level your character mid-run, giving you choices between new ball types, evolutions, passive items, or fusions. Catching two identical balls creates a fusion that combines their effects into a single powerful projectile while freeing up an inventory slot.
This creates constant tactical decisions. Do you fuse balls to consolidate your arsenal or keep them separate for diversity? Do you level up existing balls or accept new ones? The roguelike progression layer transforms a simple breakout game into a constantly evolving puzzle where each run feels mechanically distinct.
The Title That Nearly Wasn’t
“It’s Ball Pit. Just Ball Pit. There’s no X,” Sun clarified when asked how to pronounce the title. “It’s mostly a tribute to anime like Phantom Hunter. Also, X can mean fusion, which ties into the game’s theme.” Before settling on Ball x Pit, the game was titled City of Balls, which reflects the city-building focus before launch.
The development journey included ideas that didn’t make the final cut. Sun mentioned a magma ball that left lava trails damaging enemies, but once the game started scrolling vertically, the visual clarity suffered. A pet system let you bring creatures into levels where they’d gain XP, but it became redundant with character progression. Even a monkey that jumped on enemies got cut, not because it wasn’t fun but because the game was becoming too mechanically complex.
The Launch Success That Stunned Everyone
Ball x Pit arrived in October 2025 across PC (Steam), PlayStation 5, Xbox Series X/S, Nintendo Switch, and Nintendo Switch 2. The launch response was unprecedented for a game like this. 300,000 copies sold in five days. A 95% positive review rating on Steam with over 3,000 reviews. Metacritic averages between 85-89 across platforms.
Sun was visibly overwhelmed by the response. “Thank you all!!!!” he posted on Bluesky. “Been too overwhelmed for a formal announcement post but BALL x PIT came out yesterday and I’m stunned by the response! I’m very grateful to everyone who helped make it possible.” This from a developer who’d been creating games for over a decade before finally landing a massive hit.
Post-Launch Support and Evolution
Sun has been incredibly responsive to feedback since launch. Players reported hitbox misalignment issues, so he rebuilt them. Fishing rolls felt too unpredictable with extreme bad-luck streaks, so he implemented luck protection. Quality-of-life improvements rolled out based on what the community actually wanted.
When asked about future updates, Sun hinted that cut features could return. “I cut a pet system — you could bring pets into levels and they’d gain XP,” he mentioned, leaving the door open for a future update. With 300,000+ players now invested in their cities, there’s genuine demand for expanded content and mechanical depth.
The Bigger Picture: Solo Dev Success in 2025
Ball x Pit’s success in 2025 sends an important message. Polished game design and genuine creative vision still matter. You don’t need a massive budget, cutting-edge graphics, or infinite features. You need a core concept you believe in, the willingness to iterate ruthlessly, and the humility to cut things that aren’t working even when you spent months building them.
Sun spent years perfecting Ball x Pit. Each iteration removed unnecessary complexity or added mechanical depth where it mattered. The final product feels designed by someone who genuinely understood what made the experience fun and what distracted from that fun.
