Some of the entries I saw today at my old uni for #GGJ18 were great! Winning game was a bolt of electricity transmitting it's energy into other electrical appliances in order to make its way to a transmitter at the end of the level. Really cool stuff!
Third place was a fun little mix between defender and asteroids. The game itself was simple in terms of mechanics, but it was REALLY nicely polished given the 48 hour time frame. I love game jams!
