Very good level design, the abilities feel unique and different for both characters and the bosses are pretty cool!
My favourite part was maybe the fact that you had to do some quests to unlock critical items and not just find them lying around, felt pretty good!

Note for multiplayer: at least in our playtrhough, we had trouble with 1 boss only being able to be dealt with by Pampas, Selene couldn't dodge whatsoever. Only for multiplayer, it doesn't break the experience or the progression at all but may need a few tweaks for it, but 100% recomended and with 0 complains if you're going singleplayer.

Awesome co-op game.
