Speaking of ideas and Elum, I'm sure one or more of us actually felt some sort of emotion when leaving him behind. Or at least we all tried to get him past that last row of mines in Paramonia.
Anyways, the idea i'm trying to get across is what if we subtly make it that bit more sad. Not saying sadness is a good thing, but for a good dramatic effect that shows player depth/relationships, we have Abe greet Elum by patting him or playing with his face like a wrinkly puppy when they first meet.
Something to show that Elum is a friendly creature, regardless of his size, face talons and tiny vestigial Trex arms lol.
Going on from this idea, make Abes departure a sad one. For instance, when Abe gets to the point where he must part ways, he pats Elum on the head one last time and says goodbye. (separate animation from the 1st pat)
I could go further and say that when you first meet Elum, the sligs in those places have him chained up and he is just sitting down like a lazy, miserable dog and the bell opens/unlocks the chains, instead of him just appearing at the sound of the bell. But I don't want to stow away from the originality of the game and its process. Unless this is passable that is.
Let us know what you guys think
