Defold
I've been constantly searching for engine like Defold. it's lightweight, yet powerful and fast.
The scripting language is Lua. Now many people told me that Lua is not supposed to be used in large projects. Well that's no really true at least for Defold. Project management is very similar to Unity, so basically you can create as large projects as you want.

Performance
Performance-wise Defold uses LuaJIT which is itself really fast. And what about native functions? Don't worry, Defold got you covered. You can write your own native code as extensions to extend whole engine.

API
About Defold API, it's kinda "low" level. You have to write many things by yourself. But don't be scared, there are many great extensions therefore don't hesitate and just use them if you can! (don't create stuff twice) :)
I have to mention that Defolds API is very stable and that's a great thing!

Support
Devs behind Defold are friendly, helpful and constantly fixing and updating engine. The community is also friendly and willing to help anytime on forum.

So... why Defold?
Defold is complete solution for creating multiplatform games. Jack of all trades. Builds are easy, quick and small. Testing is awesome (hot reloading, debugger) It's free with wholesome support.
