No option to go back to battle menu after selecting 'Attack'
**Bug Description**:

This is not really a bug but when you choose `Attack` there is no way to go back, say if you changed your mind.


**Steps To Reproduce**:

Just start a normal battle with a wild Pokémon like this:

```
What should Charmander do?

[1] - Attack
[2] - Switch
[3] - Item
[4] - Run

> 1

[1] - SCRATCH | NORMAL - 35/35
[2] - GROWL   | NORMAL - 40/40
[3] - EMBER   | FIRE   - 25/25

> e
> q
>      
```

**Expected Behaviour**:

I think there should be a back option that takes you back to the battle menu. I'm not sure if this was done with the other options because at this stage in the game, none of them can be picked.
