A calamity is set to emerge from the abyss at the end of the year. You must prepare for it within a year while fending off assaults from two worlds. Fortunately, with the power of reseting time, the clock isn't ticking as loudly as it seems.
This is an incremental tower defense game where you manage the tasks for your personnel, gather resources, recruit and nurture 36 unique characters, and dig deeper into more floors for more mechanics.
Having your base breached doesn't mean game over, but time will be reset to the beginning of the year, with some progress retained. Resources that can't be carried back in time are converted to exchange for permanent upgrades. Continue this loop till you've prepared sufficiently to solve the problem, breaking free form this endless year.
