Difficult to Use: Many users find the engine incredibly difficult to use, with a steep learning curve and non-intuitive design. The complexity makes it harder to use than other engines, even those requiring actual coding.

Infrequent Updates and Slow Development: The software has not received updates for years and development progress is very slow. Users are dissatisfied with the lack of frequent updates and slow pace of development.

Lack of Proper Editors: The engine lacks proper editors, including a functional world editor and level editor. Users report that the available editors are barren and completely useless.

3D engine integration: The integration of the 3D engine, specifically with CF2.5, is highlighted. This feature is noted for its utility in projects.

Firefly input lag issues: Firefly causes input lag, particularly with Fusion's built-in keyboard and mouse events. This can significantly impact the user experience.

Crashes when stopping Firefly: Stopping the Firefly Engine while it's running can cause the entire application to crash or the Firefly window to freeze, leading to potential data loss and frustration.
