Number Days Sim Date is a dating simulation game made by Pacthesis. Released on December 1, 2012.

A girl named Evelyn gets stuck with 5 other people in an amusement park called "Pactheland". Going around the park and hanging with the other guys sure is fun, but the things they do have limits since their phone's battery life seem to correlate with their energy and, they have these weird numbers displayed in their phone that change whenever someone does anything. They've also been receiving these weird messages that say that their time will be over when their number reaches zero, and one giving them a clue on what's going on.
