add restarting and pausing support

[HarshNarayanJha]

I gave implemented restarting the game without quitting and pausing logics. I have also added a flag on Diddi, called is_invicible, which disables any interaction with the Fire (for debugging purposes only!)

Oh! I accidently forgot to run black/flake8 formatter. It might have some issue!?

[DiddiLeija]

Since you're a "first-time contributor" in this repo, I have to approve GitHub workflow runs.
And... seems like flake8 isn't happy :/

[DiddiLeija]

I'd suggest you these changes to get rid of flake8 issues. Haven't run local formatters yet, but I deduced the fix according to the flake8 error messages. Hope it helps 😄

[DiddiLeija]

Anyway, thank you so much for providing an improvement like this!

[DiddiLeija]

Hmm... Seems like now black is unhappy :/

[DiddiLeija]

Gonna try to run the formatters locally, to find a possible fix :)

[HarshNarayanJha]

What's the issue this time 💦 ?

[DiddiLeija]

Black re-formatted something on my local run. Gonna make a suggestion as soon as possible 👍

[HarshNarayanJha]

Oh! Finally it did, Congrats 🎉

[DiddiLeija]

Yipee! Thank you @HarshNarayanJha! 🎉

I've just tested this, and looks great. I'm going to merge this, update the guide with the new controls, and launch the fixed dists (we're still in time).

Thanks again!
