[Kioljin]

Create a sidebar menu where the player can view their score, buy, upgrade or sell towers, pause the game etc.

We could use the flower widget library: https://github.com/makotok/Hanappe/tree/master/projects/flower-extensions

src/widget.lua is the library and samples/ has some examples of using this library.
