Played this today, a few thoughts:
1) I really wish I could save. I'm not as agile as I used to be, and I died in the first area. Redoing the intro was not that fun honestly.
2) I have no idea what to do once I go to the other world. Do I just kill everything? Some sort of guidance would be nice.
3) Game hung after I killed all the slimes. Got a message talking about is this my world now, but never advanced.
