Thanks for your kind words! we’re glad you played it and had a good time! <3
Bonuses are granted depending on combos you make with items. For instance, “Ouro, FETCH!” is granted when you bring back Ouro’s collar (that’s the dog) and a stick! It means it’s a bit luck-based, as it’s perfectly possible in a complete run you won’t see an item that would be useful for a bonus :D
Again, thanks! <3
