I have bought A Matter of Murder! It looks very interesting and aesthetically pleasant, although I can't hide that it burns a bit to see somebody execute an idea you've also had better than you. Especially because the first idea I had, whenever I considered maybe expanding the game, was turning it into a point and click (I only made it a top down game because that was the style of assets provided for the jam).
Given their importance in the genre, motives are always at the back of my mind, but honestly I never figured out how to "model" them, and they were the first thing that was dropped when I moved from brainstorming to actual programming. I feel like it may be the kind of thing that is better implied rather than modeled explicitly by mechanics, but maybe I'm just being blind. I'll see how AMOM does it.
I was thinking about maybe putting my hands back in the game just this week (that's why I popped back into itch.io, which is not a website I visit often) so this conversation comes at a great time. At the very least you helped me find out about AMOM which seems to be a game I'm going to have some fun with. Thanks!
