Block/visual scripting engine only using eye track

Hi im disabled and beginner, I wanted so long make game but normal scripting is almost impossible. I saw Construct 3 but its paid. GameMaker some people said it isnt good? Godot and roblox (is belong as game engine?) has plugins. GDevelop, Unity, Unreal Engine can create full games Block/visual scripting (I think) Which and why would you recommended?
