The game in the image is just the base of a metroidvania fps game in a scene where I was testing the movement and shaders. What I'm planning for it would take a lot longer than the few days we have for the jam. I'm not too great with 3d models, but I could still try to make a 3d/fps game with simple models if that's what you're more interested in.
Thanks, the katamari game was originally a bit messy before I made it pull the pieces toward the center (link). I have an idea for a metroidvania fps game. I can just use really simple 3d models and textures. Is there a better way you want to communicate, like with skype or discord? We don't necessarily need to do a voice chat.
