does this game have a guide btw ? how do i get mom home ?
If you press the T icon in the top right you can view the in-game guide. It's pretty straight forward on what to do. There's some guides
here, and
here for 0.4.0. Most of the content can be unlocked from playing through the game's story. Then you increase their stats with gifts, meet them at specific times (usually 12 Noon, evenings for sex) in the places other than their room to go on dates, etc. to get animated scenes. Then meet at washrooms, toilets, bungalow, pool, etc. for photos or short animated scenes.
At the church you can get Faith from the 'Mother' to punish the 2 Nuns and view it at the cam in your room at a specific time (22:00 or so). Then there's the Memory Keeper, and a few other scenes with the nuns at the Nave, and at your Home further in the story.
At shops you can buy gifts to raise stats, buy costumes for certain girls to wear and do short posts or photoshoots, use the toys to caress some girls, etc.
Still can't get to bang Alice in this version 4.0?
Not yet for version 0.4.0, but Melissa is somewhat close imo.
is the to-do list in the phone not implemented yet or does it unlock after a certain point?
It's not implemented yet, so nothing is displayed.
