Yeah, i really like the "human chain" concept. We had the idea too when brainstorming but discarded it cuz we couldnt think of a way to make it into a game mechanic. You did a great job doing that! I think the though core idea is great, the actual mechanics could be improved and made more clear to the player. The visuals are simple, but it's a jam, what do i expect. :D Personally i could'nt have done any better creating game art in 48 hours. I think it would have great potential. Reminded me a little of portal bridge builder but without the bridge building part.
