Definitely keep going for those hidden aspects! The one for the bow was one of my favourites in the game and allowed for some incredible builds!
Here's a guide on how to unlock each hidden aspect if you're interested:

It's just as addicting and fun as the original game (and there is a LOT more to do, with EVEN MORE still to come).
One minor gripe I currently have is that the boons feel quite unbalanced, with Poseidon's being completely OP, while other Gods' (looking at you, Zeus) are nearly useless
However, Supergiant Games have already announced that they are re-balancing things with the upcoming first patch, so this is all in good hands.
Also, that second boss fight is probably the single coolest thing Supergiant have ever created
