Hello.
The topic of time travel made me come but I don't really know what to think about the game.
You've put a lot of thought in the worldbuilding. It's not a roaming game though.
The characters are few but their description is too shallow, even for the MC.
The plot, outside the main theme, isn't precise enough.
The images, though you've clearly put some time in the search, are a little too similar. You need more variety.
Time travel is something I'm interested in. I also tried the other games mentioned in this thread. Though here so far it's go to the past and chose who you want to screw with. You do it directly, without taking some time to get to know them. The struggles of the MC are also lacking. It was also repetitive (sucking, fucking, showering, meeting people and trying to earn something, coming back, sucking, fucking...).
Also, why would he directly try the ring. You reflect and search more informations during some time before taking the risk of going to the past. It doesn't have to be many days but he shouldn't do it right away, particularly if we chose the intelligent trait.
Good continuation.
