Dev has a main occupation, and developing games is her hobby, so she has difficulties estimating the exact date to release the android version, since sometimes her work schedule clashes with game development schedule.
Considering its the first quarter of the year, many businesses is entering busy season, so OT is common.
When the first quarter of the year is over, dev has more time to develop for android version, so it may be released in late April or early June, could be longer if she decides to add more content to the game.
