I started off the day with a bit of stretch goal planning, and what internal milestones we want in the team, and decided that at the end of the week we would aim to have a build where atleast 1 player can run around and do some form of action, be it an attack or just an interaction with something.
Outside of this planning, I and the other designer discussed the second class and finalised the design for it. It's a spear wielding DPS type character that can attack foes at medium range, and they can also throw explosive javelins at foes.
Outside of this, it was mostly me sitting and updating the GDD and planning for the friday presentation where I'm supposed to present the project for a group of sound design students who are going to take care of all of the audio for the game.
