The win message should be discardable and you could continue to look at your snakes.

There should be a way to zoom when you have very much snakes.

You shouldn't be able to crash the game with the increase population button.

It would be cool if you could view the neural networks of your snakes - maybe also edit them - it should be something you could unlock after winning?

I would like to be able to increase the field size after winning - maybe allowing a second, third, ... winning.
