Very much incomplete. :)
Might've been 1 minute over deadline?
Only uploaded Linux version before deadline, aim to upload Mac/Windows builds later.
You can play locally offline if the environment variable `TDDWU_LOCAL_PLAY` is set to `1`.
Otherwise, click the "Be Very Online" button to go online--the name/description of the dungeon is based on the dungeon/lobby ID assigned by Epic Online Services.
You can move around and attack a monster with a stick but...well, good luck with that. :)
Up to four players can be in the same dungeon but alas they can't see or interact with each other--and the monsters exist in separate space-time continuum so in this version you can't team up against them.
But, hey, a week ago this didn't exist and now it does, so that's something.
All the Roguelike-specific code was developed this week, the majority of the Epic Online Services plugin/addon for Godot code was developed previously.
