Coastal Codes
Listen. Decode. Respond.
Alone on a coastal platform, you guide sailors through the seas.
Each night, signals arrive in morse — short loops asking for coordinates, relaying alerts, or issuing warnings.
It’s your job to decode the transmissions and act on them
Made in 72 hours for the 2025 GMTK Jam with the theme "Loop"

- Nights – Learn your tools and systems one by one as you progress through the nights;
- Endless – Race against time to respond to as many transmissions as possible before your shift ends;

Hey, I'm one of your reviewers in the coursera project. Just wanted to say you did such a good work, in just 72 hours nonetheless! I really would love to play the complete game if you decide to further improve it, it was so much fun! It would be such a fun way to learn morse code as well :D
Heyy! Thank you so much!
It's kinda funny that we never intended to "teach morse" with the game, but by playing you end up familiarizing yourself with the system and memorizing some codes. It might be interesting to expand the game with this in mind...
