I made a 2D platformer with very simple controls. You could look left or right and jump forward using space, but most importantly of all, press a button to shoot a super powerful laser beam! And this isn't just any button, it is your button! You are a laser remote! Your goal is to defeat the evil scientist while dodging their chaotic attacks. Using your special laser button and jumping power, you have what it takes to take them down! It was made in the Godot game development program, in which I did all the scripting and created all the assets in Aesprite.
How much experience does your group have? Does the project use anything (art, music, starter kits) you didn't create?
I have used godot for 3 projects, all for code days. I am the only member of the team.
