Awesome idea! As others have mentioned, it's a little confusing to jump straight into the game. A way to remedy this might be to have levels, where new components are added to manage. And just a small tip for Unity, always set your canvases to "Scale with screen size" so that UI elements are the right size in whatever window size you have :)
I quite like the UI layouts, just need some adjustments for readability! Nice work! :)
