May I ask you to make two additions?
This game need an option to redefine keys and quick restart after death in the Survival.

Hi, OK. Thanks for your topic. Its almost 3 years , I make last changes in this game, but I can do that.

I thought the game was forgotten.

Thank you for your reaction!
Nothing is forgotten is Internet, someone can always come )

Also I have found a quick restart - R.
