Howdy folks! My game was made JavaScript building off the code I used for my js13k game Bounce Back. The source code is on GitHub.
I integrated the theme by having ghosts of your previous lives return to help you after each death. There is also a juggling mechanic like the Twin Bee / Stinger series of games where you can juggle an egg for massive bonus points.
The level is procedurally generated every time you start a new game and gets progressively more difficult over time. There are 2 ways to shoot, hold fire for fully auto, or wait to charge up a powerful blast.
The game can be played with keyboard, mouse, or gamepad in several different configurations. Player's high score is tracked for when they return. I have yet to break 1000 points. The sound effects use ZzFX, my tiny JavaScript sound generator.
I also used the same font and font rendering system I made for Bogus Roads.
