Whats the requirement to unlock challenges?

I unlocked it but I forgot how I did it. Anyone know? I think it tells you how when you hover it if you haven't unlocked it yet.

You unlock challenges after completing one loop (going through all 3 chapters of the game), At first you only get the first 3 challenges and by completing any 2 of them you get number 4 and 5.

Thanks! I thought it might've been the shop upgrade, "unlock more options" but I think that upgrade gives more shop options in the next shops now that I think about it.

You're welcome! And yeah I'm assuming that's what it does as well, just like in Isaac.
