Thanks so much for playing and leaving feedback. The split-screen was probably the best feature I actually finished during the jam. I totally agree with you about local co-op games which confine players to the same screen. I really didn't want the players to feel restricted in any way; I debated about pure splitscreen but I think the dynamic one feels really nice in the majority of situations.
As for the members leaving, I was not really in a super great headspace when the jam ended so I probably made a bigger more dramatic deal than it really was. Now I look at it as a lesson that I need to be more careful about who I collaborate with on jam projects.
