And I'm pretty sure you can make this game in Unity...
Game tech is basically universal for zero-graphics games like this, it's 100% "business logic". If you have to fight with the UI/display system for even a moment to make a game like this, then you're probably either using a library without enough features (which, ahem...Pygame, yeah...) or you just don't know the system well enough to be efficient.
Specifically, I want to have some fun developing a few game ideas into at least prototypes. I never really had time to do a proper analysis of Pygame, Godot, Unity etc.
Unity can create any type of game. In the end it's just helping you push vertices and shaders around.
I do agree Unreal has it's roots more in 3D character shooters. A lot of assumptions built in but you can still work around them there too.
