Actually, I like your point about the w key if its not being used. Having both space and w be the jump button sounds like the best approach.
You're right! We're marred with time constraints, we had a lot of people new to Godot and to game jams, as well as some availability problems here and there. We know it has potential and I think most of the team is motivated to continue working on this after the jam. There was definitely more writing planned and everything.
