Hello and thank you for bringing this to my attention!
As far as choices go, to get the two full routes that continue the rest of Day 3, try to avoid losing too much closeness with Noah before you reach this section.
Once you get here, 2 out of the 5 choices will continue into the rest of Day 3 depending on what you do next. For the second full route, here's a very small hint, you have to be very sneaky. >;] I'd highly recommend saving right here once you reach a high amount of closeness with Noah.
The first full route starts in the morning with the player(Y/N) being woken up by a noise.
The second full route starts in the afternoon with the player(Y/N) waking up normally. (This one might be a little tricky to find.)
As for the build, if the following screenshot looks like this within your game, that's from the March 2023 demo and won't have any full routes. A lot of CG's were updated and no longer in the [Extended Demo]:
If you're still having trouble/issues please let me know! :]
