The engine is cool. Every API is directly exposed and callable, so there’s no need to deal with bloated OOP abstraction/interface nonsense. However, the sprite tools don’t have a color palette system, which makes drawing animated sprites a bit painful. The code editor also doesn’t support indenting selected code with the Tab key. Pressing Tab after highlighting code deletes it instead, so if you want to properly refactor or format code, you’ll need to open it in another editor.
