About the Studio
The story and philosophy behind Ace Horizon Studios.
Marcos C. Nunes
Founder & Lead Developer
Ace Horizon Studios is a one-person indie studio based in São Luís, MA — Brazil. I design, code, and ship everything — from full games to developer tools.
I believe indie games don't need massive budgets or huge teams to make a big impact. With the right systems and architecture, a solo developer can create polished, professional products that compete on quality and fun.
My technical focus lies heavily in roguelike systems, procedural generation, and building extensible tools that not only power my own games, but help other developers ship faster.
How I Work
Ship, Then Improve
I prioritize getting quality products into players' and developers' hands early, then relentlessly iterate based on real-world feedback.
Build Once, Use Everywhere
Complex systems I build for my games become modular, reusable assets. CraftCards and CraftMaps were born directly from Red Pistol's architecture.
Clean Architecture
Every line of code is designed to be maintainable, extensible, and thoroughly documented — because future-me is my only teammate.
Quality Over Quantity
I'd rather ship one highly polished, bug-free product than five mediocre ones. Every release represents the absolute best work of the studio.
The Journey So Far
CraftMaps Launch
Released the procedural roguelike map system on the Unity Asset Store, allowing devs to implement Slay the Spire-style progression in minutes.
CraftCards Launch
First standalone Unity asset published — a complete drag-and-drop card UI and deck management system built from battle-tested code.
Red Pistol on Steam
The studio's debut title launched globally. A post-apocalyptic bullet-hell roguelike that set the foundation for all future tech.
Studio Founded
Ace Horizon Studios was officially born in Brazil. Pre-production and core system development for Red Pistol commenced.
