How effective is the GameMaker + Lua solution?

Question

Game development

I found GML to be very impractical, which is not the case with Lua. As a result, it was decided to connect Lua through an extension. Here is the documentation for it. How effective is such a solution? Where and what can be pitfalls and how to deal with them?
It is planned to write the core of the game (all logic) in Lua, and use GameMaker's functionality as a graphical and network API. That is, it is drawing tiles, sprites, animations, GUI, playing sounds, exchanging packets via sockets - and that's it. And all game algorithms and data structures are in Lua. I'm afraid that such a bundle may not be effective, but I don't fully understand where the weak point could be.

Answer 1

If you want Lua, then why not Defold?

Answer 2

Back in 2008, GM was good for beginner developers
But now it's 2018, I highly recommend getting to know Unity, and C# is amazing
