There's space in tools like Godot, which has a relatively stable API, tight and helpful integration with its custom scripting language as well as support for both C# and C++, solid docs, first-class support for 2D, the ability to export to mobile as well as web and desktop, and the ability to toggle between a continuous rendering mode suitable for games and a reactive rendering mode more suitable for apps. GameMaker, too, has a very stable API for its proprietary scripting language and, though it is made with 2D gamedev in mind, can work just fine for simple apps for personal use. Defold is worth mentioning as well
