A mini Global Game Jam 2019 entry by Javier Arevalo.
The theme is "What Home Means to You". This minigame is of course a riff on the classic Jet Pac by Ultimate, the game that made me decide to become a game developer when I was 13 years old.
Your goal in the game is to pick the magenta fuel cells that drop and put them in the rocket (gray rectangle), and repeat. Kill the orange baddies before they hit you. Difficulty steadily grows in procedural fashion until the game likely becomes too hard.
Controls for left, thrust and right are keys A/W/D, O/Q/P or arrow keys. Shoot with Space, Control or M or S. I also implemented mouse control and touch controls for mobile devices. It's harder to play like that, but all things considered, it kind of works.
I did not get to implement graphics or most metagame niceties like game over, multiple lives, rocket takeoff or such. I spent about 3 hours on the game, one hour on mobile & compat, and one hour on misc stuff, spread in haphazard half-hour sessions over the GGJ weekend. I made reasonable efforts to get this to run well on all web browsers, including mobile browsers and the app-like shortcuts you can create on iOS and Android.
This minigame is written in the most oldschool way possible, mostly globals and functions. This is intentional, to sort of exercise parts of my coding brain that are normally dormant in favor of OOP and reasonable software engineering practices. My natural tendency immediately would be to start abstracting and make a basic OOP framework to build on top of. Make a vector type, a rect type, all objects share these basic properties, collision detecting based on collision groups, virtualized collision response, etc. Yeah that's better software design but by now it's all so automatic in my head that there's nothing to gain from doing it as an exercise.
