  • 2D and 3D Unity game features
  • Custom gameplay mechanics
  • Character controllers and player systems
  • Combat and weapon systems
  • Inventory and item systems
  • Enemy AI and NPC behavior
  • Quest and progression systems

I can work with 2D, 3D, single-player, and multiplayer Unity projects, depending on your requirements.


If you already have a prototype or existing game, I can also help add new features, troubleshoot problems, improve gameplay systems, and optimize your project.
