For some reason it was NOT obvious that I could use the radio to switch back to the first player. I thought, "weird that this guy got vitiligo and experienced a time jump. oh well, game jams are weird."
After I figured that out, the game felt a lot better, but I definitely got stuck for a bit. It was kind of cool to have the player actually play the part of communication by finding the answer as one character and the player knowledge transferring to the other via radio. Neato.
Very well done. This looks really polished. I loved the floppy zombie arms and slap animations for everything. It undercut the mood slightly, but it also felt like a breath of humor to lighten it up between the otherwise somber exploration moments. Good job!
