I just submitted my game "Tiny Planet Defence League". It's a tower defence game where you defend a tiny planet from asteroids and alien spaceships. You can check it out here: https://bennydgames.itch.io/tiny-planet-defence-league.
I've been following the various GameDev.tv courses on Godot and Blender for the last few months, but this is my first time entering into a game jam and developing something from start to finish. It's not quite as polished as I'd like it to be, but it'll do for a first attempt :')
I hope everyone else's game jams have been going well - I'm excited to look through everyones projects this week!
