Inspiration
Tower defense has always been one of my favorite genres. I grew up playing Plants vs. Zombies, later got hooked on games like Bloons TD, and loved how they turn simple placement decisions into surprisingly deep strategy. Meowcenaries™ TD comes from a much older idea I had in school: a tower defense game about cats defending their world from chaotic, animated threats. This competition finally gave me the push to turn that long-running idea into a clear, production-ready game concept.
What it does
Meowcenaries™ TD is a tactical mobile tower defense game where heroic cats defend their kingdom from The Mess, a supernatural force that manifests as living yarn, slime, vacuum war machines, and ghostly fishbones. Players place and upgrade distinct cat defenders, adapt to new enemy behaviors, and balance short-term survival with long-term economy and upgrade choices. What makes the game stand out is the interaction between enemy families: Slimes can affect Yarn enemies, Vacuums can carry both Yarn and Slime threats, and each wave asks the player to respond to overlapping pressures instead of isolated enemy types. The goal is to create fast, satisfying sessions with a strong “one more round” pull, while giving the game its own identity through a Cat Kingdom setting, a storybook diorama aesthetic, and a readable but expressive enemy ecosystem.
How we built it
Because this is a game design competition, I approached Meowcenaries™ TD as a complete pre-production package rather than a fully built game. I started by defining the core loop, enemy escalation, and mobile-first gameplay goals, then developed the project across four connected artifacts: the Game Design Document, Player Journey Map, Visual Concept Package, and Production Plan. From there, I refined the worldbuilding, unit roles, UI direction, map concepts, enemy interactions, and MVP scope so the entire package told one coherent story about a game that is ready to be built.
Challenges we ran into
One of the biggest challenges was balancing familiarity with originality. I wanted Meowcenaries™ TD to feel instantly readable as a tower defense game, while still standing out with its own theme, world, visual identity, and enemy ecosystem. Another challenge was scope: the ideas naturally expanded quickly, so I had to stay disciplined about what truly belonged in the MVP versus what should be saved for future versions. Keeping all four artifacts visually and mechanically consistent was also a major focus, especially when refining the Player Journey Map, storybook diorama visual direction, and production plan to support the same core experience.
Accomplishments that we're proud of
I’m proud that Meowcenaries™ TD now feels like a cohesive game instead of just a fun premise. The Cat Kingdom setting, the supernatural identity of The Mess, the mobile-friendly gameplay mockups, the storybook diorama aesthetic, and the defined MVP scope all support the same vision. I’m also proud of building a starter roster of cat defenders with clear tactical roles, creating an enemy lineup that escalates in both personality and gameplay, and defining cross-enemy interactions that help the game feel more dynamic and distinct. Most importantly, the project now has a much stronger sense of what makes it worth playing beyond just “cats in a tower defense game.”
What we learned
I learned how important scoping, clarity, and consistency are in early game design. A strong idea becomes much more convincing when the core loop, progression, visual direction, and production plan all reinforce one another. I also learned that mobile-first strategy games need strong readability at every level, from map flow and tower silhouettes to UI hierarchy and pacing in the first 15 minutes. Finally, I learned that the best design choices are usually the ones that make the player’s decisions more meaningful, not just the ones that add more content.
What's next for Meowcenaries™ TD
The next step for Meowcenaries™ TD would be building a focused vertical slice that proves the core loop in play. That means one polished test map, a small starter roster of cat defenders, a seven-enemy MVP lineup, basic upgrade paths, wave progression, and a first boss-style stress test. From there, future development would expand the campaign, add more maps and cat classes, deepen progression, and introduce later-game threats and events. The long-term goal is to turn Meowcenaries™ TD into a replayable mobile tower defense game with strong identity, strategic depth, and room to grow.
