How do i access act 5? I finished all events in act 4 and finished stories for both waifu house girls. Unlocked the lab, but don't know how to preogress with the main story?
The Fourth Act is still in development. At the moment, the public version has the Level 4 events for Ash and Hinata available. After opening the lab, you need to complete the event for Ash, which starts the Fourth Act. Then, you can complete Hinata's event. The phone notes contain hints and requirements for all the events.
