Hi!
A fun idea! I would say that it got a lot of potential and I think this is a well thought trough idea for this kind of jam. The main issue I found for me is that I did not really get my own orientation in a good way when my mouse aimed and I moved with WASD. For me personally I would go for a W and S control only and make the movable direction to be in the look direction. But its mostly for my own liking
But it is a fun game and I think you can go far with this if you continue working on it and adding small bits and get people to playtest. Keep it up and Im thrilled to see this expand!
