I love the deadpan nature of the voice acting, and I think your use of SFX really captures that early-2000s MMORPG aesthetic. I kind of wish there had been an indicator of where I was going & attacking when I clicked, but this is not a game-breaking omission.
I think y'all could make a really cool adventure game on this framework if you added more levels and challenges. The idea of using voice-chat to influence -- but not control -- your AI partners is a strong one. I think you could make it stronger if you had different avatars for the different characters (could even let the player choose their own), but I understand that time constraints are a factor in a jam game.
Overall, great job. Keep up the good work!
