An eight-player text-only SMS game of foot-to-foot (no punching) combat on an Atlantic beach. The players each try to defeat the others and be the last one standing, while using the crashing waves to their advantage.
A Ruby application running on a Linux server that uses the Twilio API; no special software required for the players, although standard messaging rates apply.
Install Ruby and the necessary Twilio API gems, then set the following environment variables before running: TWILIO_SID, TWILIO_TOKEN, and TWILIO_NUMBER. Twilio and carrier message pricing applies, so be careful!
