Rescue Time is an NES homebrew game that takes inspiration from time-travel stories, specifically Back to the Future. The story starts with a genius named Austin using a time machine he built to send his friend Joe into the past. However, he is unable to bring back Joe with the machine himself and decides to send a boy named SJ to the past with a personal time-traveling watch that's powered by NES cartridges. It's now up to SJ to rescue Joe before his watch runs out of power and sends him back to the present.
With the help of a warp spot, LoganTheTASer and ShesChardcore prevent a time paradox from happening in record time.
