The indie game development cycle is often romanticized as a journey of passion, but for Martin Nerurkar, it was a five-year marathon that nearly broke him. After the release of Nowhere Prophet, a tactically dense deck-builder praised for its atmospheric world, the Ludwigsburg-based developer faced a reckoning: total burnout. The exhaustion led to a multi-year hiatus from video games, during which Nerurkar pivoted to the slower, more intimate pace of tabletop role-playing game design.
Now, Nerurkar is returning to the digital screen with Sharkbomb Studios, unveiling a project that feels like a deliberate reaction to his previous struggles. Crownbreakers, a “tactical card brawler,” has officially launched its Kickstarter campaign. The game attempts to bridge the gap between the cerebral, often static nature of card games and the visceral energy of a side-scrolling fighter, all set within a “spiritpunk” metropolis where magic is harvested as a commodity.
Unlike many Kickstarter campaigns launched out of desperation, Sharkbomb Studios enters the crowdfunding space from a position of stability. Nerurkar has confirmed that base funding for the game’s development is already secure. The campaign is instead designed as a community-building exercise and a means to expand the game’s scope—specifically adding more original music, expanding the card pool, and deepening the narrative layers of a world defined by “modern greed.”
Kinetic Strategy: The “Knockback” Mechanic
At its core, Crownbreakers is a single-player experience designed for “snappy” sessions lasting between 20 and 40 minutes. While it retains the deck-building DNA of Nerurkar’s previous work, it strips away the slower pacing in favor of environmental interaction. The centerpiece of this shift is the Knockback mechanic.
In most card-based tactics games, the battlefield is a backdrop. In Crownbreakers, the battlefield is a weapon. Players can use specific cards to physically manipulate enemy positions, slamming opponents into explosive barrels or crashing them into one another to trigger chain reactions. This introduces a spatial puzzle to the card game: it is no longer just about which card is played, but where the enemy is standing when it hits.
The gameplay loop is further augmented by a “Momentum” system, which dictates how quickly a player can push through a district to reach the boss. To keep the action from becoming repetitive, Nerurkar has implemented a mid-run deck-building system. Rather than retreating to a menu, players smash open treasures during combat to acquire new cards, relics, or “stickers”—customizable upgrades that fundamentally alter how a card functions.
| Feature | Function | Gameplay Impact |
|---|---|---|
| Knockback | Positional Manipulation | Environmental damage and AOE combos |
| Sticker System | Card Customization | Player-defined ability modifications |
| Momentum | Progression Metric | Determines speed of boss encounter |
| City Hub | Meta-Progression | Questing and champion upgrades |
From Burnout to “Spiritpunk”
The thematic shift in Crownbreakers mirrors the developer’s personal evolution. While Nowhere Prophet was an exercise in tactical depth and atmospheric solitude, Crownbreakers focuses on community, vulnerability, and the fight against systemic greed. The “spiritpunk” setting—a collision of soul-powered magic and industrial capitalism—serves as a backdrop for a story about dismantling empires built on the exploitation of others.
As a former software engineer, Nerurkar’s approach to game design often balances technical precision with human emotion. The break he took from the industry allowed him to explore TTRPGs, where the focus is on shared storytelling rather than rigid systems. This influence is evident in the game’s “Beyond the Battlefield” segments, where players return to the city to interact with champions and fulfill quests for local communities, grounding the high-concept combat in human relationships.
This transition marks a shift in Nerurkar’s philosophy. By focusing on “games that matter,” Sharkbomb Studios is attempting to create a project that is sustainable for the creator while remaining challenging for the player.
The Logistics of the Kickstarter
The crowdfunding campaign offers a tiered reward system that ranges from practical access to thematic satire. Backers can secure early alpha access or the opportunity to co-design relics and cards, effectively becoming part of the development process.
Notably, the campaign includes a “Capitalist” tier. In a nod to the game’s themes of modern greed, this high-priced tier offers very little tangible value, providing only a “shiny thank you plaque” in the credits. It is a meta-commentary on the very nature of luxury spending and the “soul trade” depicted in the game’s narrative.
For those following the project, the primary goals of the funding are clear: increasing the volume of content and the quality of the audio-visual presentation. By leveraging the community now, Sharkbomb Studios aims to avoid the isolated development cycle that led to previous burnout, opting instead for a transparent, feedback-driven approach.
The next major milestone for Crownbreakers will be the opening of the closed alpha for backers, which will provide the first public look at the Knockback mechanics in action. Official updates and backing options are available on the Kickstarter platform.
