This weekend I was at a GameJam, where we had to make a game in less than 48 hours!
I was the only programmer in my group, and we made this game called “FireFireMadness” 🙂 It is a game where you have to master your fast key-pressing skills and memory, to defend the city against Godzilla (who can shoot lasers!). So you have to remember a combination of keys, and do them within a time limit.
