Possible disadvantages

• Limited 3D Capabilities
  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.
• Smaller Community
  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.

• User-friendly
  ImpactJS provides a user-friendly structure for developing games, making it accessible for beginners and simplifying the development process.
• Level Editor
  It includes a built-in level editor called Weltmeister, which allows developers to create and manage game levels easily without external tools.
• JavaScript-Based
  Being JavaScript-based, it allows developers to leverage their existing web development skills and integrates well with other web technologies.
• Broad Browser Support
  ImpactJS games run in the browser, which means they are cross-platform and can be played on any device with a modern browser.
• Active Community
  There is an active community around ImpactJS that offers support, plugins, and resources, which is beneficial for problem-solving and enhancing projects.

Possible disadvantages

• Paid License
  Unlike some other open-source game engines, ImpactJS requires a paid license, which might be a barrier for hobbyists and small developers with limited budgets.
• Not as Feature-Rich
  Compared to some other game engines, ImpactJS might lack certain advanced features and tools that are available in competitors like Unity or Unreal Engine.
• Limited 3D Capabilities
  ImpactJS is primarily a 2D engine, so developers looking to create 3D games will find its capabilities limited.
• Less Modern Frameworks
  With the rise of more modern game development frameworks and libraries, some developers might find ImpactJS a bit outdated in terms of technology stack and capabilities.
