This is a crazy project to make for a gamejam. I like the upgrade system, but the movement feels really slow. Like hitting things and moving. The 8 directions don't always feel that intuitive, but that's something you could get used too. When I played it, it was only me and one other person online, so maybe that's why it felt empty, with more players the combat and movement would probably feel better!
I wish I had the patience to check out what 35 souls give me, maybe i'll come back someday with some friends!
Still impressive game from a technical standpoint!
