My entry is called “Cathode Ray”. It’s made in Java with LibGDX and a custom framework I’ve made that can be found here.
Basically, you control a single electron in a Cathode Ray Tube, and your goal is to direct it to the end of the tube by altering it’s trajectory with a magnetic field, so it can display the words “ENTIRE GAME” on a single CRT screen.

All the gameplay has been coded, so tomorrow I can focus on making levels (haven’t decided if I’m going to have a really long level or multiple different levels yet..), music, a tileset, and then nonessentials like a title screen and an intro.
