Congrats from me too. I didn't even know that Shadow was still the top team, there goes my last crown then... Muitos parabéns! :)
You never know. But just a little tweak is very improbable, just understanding my own bots' code could take a very long time...
Hah, I know how that goes. I commented a lot more then I used to and I still get lost in my code after a few months. I would be scared to take a look at one of my older robots (like Seraphim).
It happened with me too.
My solution: build another bot from scratch.
Already knowing what works and what doesn't helps a lot in building a competitive bot quicker and in a more organized way.
