Here is a little update about what we have done since this morning.
Maxime have been working 2d assets. As you can see here, getting the right references is always important!

Meanwhile, Paul was discovering pathfinding and variables on Game Maker and I was trying the tiles system :

But as we are not planning to have an open world, but (luckily) a couple of levels, we might just drop the tile building and layout and use a background image. Yes I know, but today with all the ram we had, who cares?
Here is a preview of the current line up of characters. You play Georges, the other ones are NPC.

About references, Tim here on the left might be inspired by another famous Tim 
And finally a sneak peak of one of the gameplay mechanics we might use: an old fashion dialogues boxe with multiple choices ! To be able to fullfill your bloody pulsions you need to have the people alone in a room but you also need to prevent the others to find out what you have done. This is where the dialogues came in to make you try to influence the NPC behaviors.

Good end of day one to everyone out there ! 
Cheers
Maxime, Paul and Flavio
