Just finished it the other day - the time loop kinda took away from the experience for me tbh, towards the end I was rushing around being like “gotta do this in 20 minutes or I have to start all over”. Kinda detracted from the chill space exploration. Still a cool game.
I found the opposite, because of the way things changed and I knew so little going in the time loop added so much. I had like four different theories as to why the sun was going supernova and how to stop it. Then going through I tried to stop it on the next loop by visiting the place I thought was responsible. Or if I couldn't get there I would just chill and go check out a different location.
