Very nice game engine!

Defold is lightweight and user-friendly with interactive tutorials, but it lacks many features other engines provide, including a physics engine.

Key issues:
1. No auto-completion for user-defined functions or message-passing interfaces, forcing you to memorize names or constantly check scripts.
2. Tabs can't be moved to separate windows, and having two open tabs feels cramped.
3. Creating a GUI object requires a separate GUI script every time, which adds unnecessary repetition.
4. Input setup lacks a key-listening function; you must manually pick keys from a large drop-down list.
5. The "redo" shortcut doesn’t work, though "undo" does.
6. Tutorials encourage bad practices, like putting everything in a single "main" folder.
7. Lists (e.g., input bindings, animation groups) can’t be re-ordered, making large projects messy.

It's decent for small projects but may frustrate experienced devs.
