Yes, Wings of Genesis is technically a sequel, but it's more of a spinoff, with completely different gameplay. There is a Ge.Ne.Sis 2 (or expansion whatever) in the works, but idk when that comes out.
I think there should be an sp and gold bonus for fighting groups. For example, one dog gives, for example, 20 gold and 10 sp. 3 dogs should give more than 60 gold, and 30 sp. maybe like 65 gold, and 32 sp, it doesn't have to be a lot, just enough for it to be a bonus.
I've been spamming the trible sawblades on the big green slime, which has a -100% resistance against death. I've yet to see it insta-kill. I think that might be broken.
