It's been a while since I joined any jams or helped with a project so I hopped into the first mildly interesting jam I saw. I've grown a lot as an artist and programmer, so I will make my first jam submission, Cards 'n Bullets, resemble what I originally wanted. I am now unbound by the 10 second rule.
Honestly surviving the unholy god of tic-tac-toe and blowing up space ships with a kazoo has been good practice in figuring out how to make code more efficient.
Good luck on the dungeons!
