My Jam entry (first real game jam ever!) is called Stay Afloat. I just published it: https://ldjam.com/events/ludum-dare/50/stay-afloat

You are a robot of last years model. Your manufacturer wants to sell new robots, so they send out updates that drain your battery. Your only chance is to get to the last point on Earth with no Internet connection - the tropical island of Nowifi. Unfortunately your plane crashed just before getting there. Jump between floating (but sinking) debris, and manage your power usage so you don’t run out of battery.

The game can be played on Unity Play: https://play.unity.com/mg/other/stayaloatfinal
