I guess you mean even numbers, Urbs.

From what I quickly tested, Death Controller doesn't really work with 3+ hearts in CTF. And even if it did, players wouldn't always be able to be see how many hearts they really had or be able to get more carrots when they see they have 3 hearts. The best alternative to using a program like Death Controller is to include levels with no powerups and at least 3 carrots.
