I draw debug rectangles and text on the screen the basic way. 
Kinda. I have this tagged union and I play with the string:

```d
foreach (ref e; game.entities) e.call!"draw"();

```

I also copied the thing on the video almost 1-1 lol.

```d

void members(T)(ref T data, int labelWidth, bool 
canShowPrivateMembers = false) {
```
