One of the game's most complex systems, pregnancy, is triggered when Leah incubates eggs. The system is integrated into defeat scenarios and becomes more prominent from version 1.30 onward. The Parasite Worm infection actually blocks pregnancy, adding a strategic layer to managing your status effects.
Version 1.10 added the ability to import/export save files, allowing for easier cross-device play (PC/Android). insect prison remake wiki
