    While Defold does support 3D development, its capabilities are limited compared to other engines like Unity or Unreal, which might not be suitable for complex 3D games.
  • Steep Learning Curve for Advanced Features
    While basics are easy to grasp, mastering advanced features requires a significant amount of time and effort due to a lack of extensive tutorials and examples.

    The Defold community, although supportive, is smaller compared to communities for other game engines like Unity or Unreal, potentially limiting collaborative opportunities and third-party resources.
  • Editor Limitations
    Some developers find the Defold IDE lacking in advanced features that are available in other game development environments, which might hinder productivity.
  • Dependency on Lua
    The necessity to use Lua scripting can be a downside for developers who are not familiar with or do not wish to learn this language.
  • Less Asset Market Support
    Compared to other popular engines, there are fewer ready-made assets and plugins available for Defold, which can slow down the development process.
