I m giving a 4 because it is well made, with plenty of options to perv out too.
That said, I hated it. I think i had resets somewhere in the 20s, and i never got past day 3. I ended up deleting it and adding it to my never download again folder. That is just me though, if you like complicated puzzles, you will love it.
It does have a hints system, but it is just that, a hint, not an answer or direction. You will need to do every option to get a clearer picture of how to proceed, and how the mechanics work.
The models and animations are good, and they are not all one body type, another plus.
The backgrounds are a bit lax, but i dont remember seeing reused ones. Sorry, that isnt fair... the backgrounds are good, art is great, they just are a background only, the models arent apart of them. That is a playstyle.
The mechanics themselves are new and interesting, definitely worth a try just to see them.
I dont remember music, but could be mistaken.
Spoilers:
My advice, have a third option for hints and cheats that really make the puzzles retarded easy. A good example: instead of have ??? for an event, describe it and how it needs to be done to complete it, then cross it off or highlight it or something to show completed. it took me 4-6 resets to figure out that I needed to let Dana get hit and just watch it happen. It took another 3-4 resets to figure out I needed to ask the receptionist about mom before I could even ask about Dana. When I saw that I then needed to figure how to find out about her family, frustration won out, and the game was deleted.
The puzzle is interesting, because you have to think in an extra dimension, or just grind it out event by event.
Keep going, you will have tons of fans once you start fine tuning your logic. Thanks for sharing your hard work,
