Is there any relationship stats or varied story paths based on selections in this game, ...? being railroaded to scenes that have varied paths based on being less agressive or more considerate. ...
This, so much. Pretty much a VN, perhaps endings going to branch off at some point. Dev did sth else for a while and came back to to that game recently. So there's one main route, maybe some paths forking later on. Maybe some fillers into older parts, too (other devs do this, so why this dev shouldn't?). One example is the computer, which is useless atm, will let you do things later but not break main story plot - just a guess though.
Good news is, you cannot really miss sth right now, it will trigger. Bad news is, no choices that make a clear difference. Don't need play a whimp to get into knickers of the gals, be bold without suffrin' bad consequences. For now.
