Game Design Document

  • Introduction

    Game Jam we have ~25 hours to log to submit a functional game.

    We will have to learn some things in odin along the way but maybe that can be included in some game design aspects through idioms and gameplay.

    I plan to make it my black pug dog the main character so I'll need to make his sprite and want to make it horror-ish genre and audio centric features, also make it hard to beat with enough play-testing.

    I want to include some basic ML from scratch in Odin if possible.

  • Background

    I participated in last years but never finished with that intent and now I do want to finish but yea not a heap of time left.

    I want to also stir up my progrramming skills with AI left behind. Arbitrary code is lame. Artisinal code, yea thats more like it. Lets make it irreplaceable because its yours.

  • Description

    Okay so Odin dog is who you play as where he is a wacky little fella with a hole lot of courage. He sneak around and he run when he hears or sees a scary.

    Odin interacts with the world in silly ways and can collect items for toggleable skills

    Maybe even take some cues from the official dorohedoro game.
