This just has to be the worst and most pointless sandbox mode in any renpy game.
So first off, the navigation through the button in the top-left to access the different areas is pretty annoying.
Click on any room, time passes. Even if you choose to "leave" right again.
Locations with available events / tasks are supposed to be marked with a (!) icon. Which is great, until they don't, and you have to click on every location at every daytime to find more content. Any form of indication which character could be found in which room at the current daytime is probably the missing key feature here.
Then again some locations don't seem to advance time when nobody is there, so you have to pass time somewhere else. If you actually realize which daytime it is.
Also, several quests can't be completed, like the "Colony" quests where you're supposed to talk to Cassandra but the only option is to "leave".
Ultimately, i don't understand why this dev keeps making these fake sandbox games. There's nothing to actually do, nothing to decide, the MC always acts on his own like when he puts on a condom for no reason (unless the women tell him to not use one, what a great corruptor he is).
All sex scenes are simple one-shot events. Only choices you really get are the "romance / corruption" plots which are always the same scenes with different text.
