Are you planning to use Construct 3 only?
Oh not only but it doesn't matter what I use. I have used numerous game engines and programming languages. I created the Christmas platform game in Construct 3 just to test out C3. That was the first time I had ever used it. I just like to try "new" game development environments from time to time.
I do like Construct 3. I found it to be highly logical and easy to work with and that is saying a lot coming from someone who typically doesn't like any visual programming environment. I generally like to just program it all myself in a code editor. My defense game I programmed in AppGameKit. I've developed with Monkey X, Unity (for 3 years but it isn't my favorite by any means), HaxeFlixel and just many many others.
I'd say what I will developing in will be a combination of Construct 3, AppGameKit and Godot at least for the near future. Godot is because I will do a 3D ultra low poly game occasionally as well. But that will be later on. And I am not 100% on Godot. I only know a friend who was checking into 3D alternatives to Unity recommended I do a 3D game in it to try it out because they liked it much better. So I will do that sooner or later.
