Building game development tools and games.
Games
Weapon Toss
Toss. Bounce. Repeat. A fast-paced roguelite where you toss weapons at waves of enemies. Every throw counts. Every bounce matters.
Swarm Survivor
Evade. Evolve. Exterminate. A space survivor game where you face endless insect hordes with an arsenal that grows deadlier each minute. Every upgrade is a power spike. Every swarm is a new threat.
Lucky Pick
An idle mining game where every click could be your lucky break. Throw pickaxes at rocks, collect gems, and convert your haul into coins, then spend those coins to build the ultimate mining operation.
Tools

Design and simulate Game Systems. Validate progression, economies, balancing and randomness. Before you ship.
ExploreAbout Espada
Espada Studio is my personal toolkit turned into a product.
After more than a decade working as a Game Designer specialised in systems, economies, and balancing, I kept running into the same problem: the tools I needed didn't exist, or weren't intuitive enough to use.
So I started building my own. Fast prototypes. Debug utilities. Economy planners. Simulators. Over the years these internal tools became the backbone of how I work.
Espada Studio exists to turn those private tools into polished products so other designers can work faster, think clearer, and build better systems without reinventing everything from scratch.
