Game Developer | Game Designer | Project Lead
Hi! I’m Don Keiser, a 22-year-old game developer with 3 years of experience working in Unity (C#). I’m currently in my third year of a Bachelor in Game Development at La Horde, a French higher education school specialized in video game creation.
I’ve worked on both solo and collaborative projects, often taking on the role of developer, game designer, and project lead.
I focus more on Game Design and Project Management.
I'm also passionate about interactive narrative design and alternate history worldbuilding.
- Game Design – Mechanics, Level Design, Lore, Systems
- Team Management – Planning, Leadership
- Game Development – Unity, C#
Most of the games showcased on this GitHub were developed in 2 to 6 weeks — either solo or in small teams — as part of academic or personal challenges.
While these prototypes are often unpolished or incomplete, they showcase:
- My ability to develop under tight deadlines
- Experience working within multidisciplinary teams (artists and developers)
- Leadership and planning skills as project lead
🔧 These projects were key to my growth as a developer and collaborator.
Beyond game development, I’m also the creator of “Kui Öösel Saabub” (“When Night Falls”), an alternate history universe focused on cultural, linguistic, and Points of Divergence in our history.
This passion project has led to the development of several mods for grand strategy games:
- 🛠️ Victoria 2 – focused on the 19th century part of the KOS
- 🛠️ Imperator: Rome – Cultural, regional, and religious overhauls
- 🛠️ Additional narrative-driven content in development
- 🛠️ A future mod of Europa Universalis 5 - focused on the 14th century part of KOS
This work blends narrative depth, system design, and historical logic — and is a major part of how I explore worldbuilding through interactive media.
