I'm curious, why are you using unity when so far it seems kinda like a slightly gimped ren'py game; there's no roll forward, the save previews don't show the ui making it hard to tell which save is which (especially being a free roam vn), there's a "quick load" menu but I can't tell how to quick save or if you even can at all, there are many times where you can't save due to the quick menu and cog button just going away and esc doesn't do anything, and the rollback (seemingly at random) doesn't go back at times meaning if you want to go back (because you can do things out of order, e.g. going to a 2nd other dimension with roxy for the first time and the internal monologue implies you've been there several times already, or the bridge with nate where you've apparently already done things with roxy by then yet you have to have been to nate's in the 2nd roxy event to access a prior nate event but can go straight up to the bridge one and do that out of order) meaning if you decide you don't want to do that yet you have to load a save and replay bits rather than just rollback to before starting the "event"
I admittedly haven't gotten that far in and am enjoying it, it's pretty fun story-wise so far (ignoring todd in the intro)
it just feels worse off for being in unity rather than ren'py, it doesn't seem to be live rendering anything and it's definitely trying to function very similarly to almost every ren'py game I've played, and because of that it leaves me missing simple things for example I'm pretty used to using right click to access the save/load and settings menus but the only way to access the menu is clicking the onscreen button and it isn't there at times and quick-load and quick-save would be useful for easily going back if something is clearly out of order and you want to find the thing you've missed before getting back to that character's story
like I get that it's free and that there's most likely just one person working on it so duh it's not going to be perfect but as I said in the first 2 words "I'm curious"
edit: I just played a bit more and my quickload menu has saves in it that are all beds, is quickload just auto saves at the end of a day? in which case it's impossible to tell which is which especially if you reload at any point
