Challenge seeds

In this guide I made a list of seeds and the corresponding modifiers.
I will keep updating this guide with new seeds as I play.
Feel free to add seeds with descriptions in the comments, I can add those to the guide.

Yeah, I know all those, but having various positive-only semi-random traits would be just better. Zen is too easy and it's a harsh transition from this to regular play. It's a bit sad that the system apparently doesn't generate/allow those at all.

@Mr. n If she plays on her own account (might have to buy game again, most of the enemies will not have started spawning yet. Also there is a zen mode, it makes it less stressful for new players.

@ladee Thank you!

@Mr. n I don't think I have to be honest, sorry.

Have you encountered any seeds that have only positive/neutral effects? I'd like to add some variety to the game without making it too hard, GF is still learning the ropes :)
