Ok first of all that's insane for a 2 week jam, great art and very good implementation of the theme!
now some feedback:
1. I personally didn't like the turn base movement, I feel this could work better with regular movement, and I felt the the controlling system with the 8 directions is very annoying.
2. I feel that if you wanna keep it tile based maybe the use of mouse to select where to move or attack might be better.
3. you need to add feedback sfx and animations to the mob attacking asap, i know its probably because of the time constraints and because you made a FCKING MMO for a game jam, but you gotta fix that asap I feel like I'm attacking air
also what backend you use for the sever/s? everything feels real smooth!
well fcking done dude you're putting us all to shame :(
