Okay, finally got it downloaded and extracted.
-The SE volume is super high. I had to lower it to 20% for it to be bearable.
-The writing was a bit flat. Like everything I needed to know was just kinda told to me. Not bad, just meh.
-I know you've said a lot of bugs/issues are unite problems, but the font was really weird, and the text boxes are super hard to read. In general, my impressions of unite are not great.
-The bust art was nice, but the 3dish models and MZ style rtp did not go well together. I would have honestly just used the MZ rtp for this one, or at least changed the tileset.
-Title screen music was good. The other music....not so much. In addition to being really loud, it got annoying really fast.
-The bartender changes appearance after you talk to the queen lady. He also starts his walking animation, like he has the "stepping" box checked.
-I played up until the barrel puzzle. The torch memory puzzle was okay. It felt kind of like filler, IMO, but maybe it's because I don't like puzzles like that in general.
-As for the barrel puzzle, I have no words. I'm guessing it's some sort of lost woods (from zelda) type thing? I don't know. Wandered around for quite a while trying to figure it out, and than I got frozen in place for some reason.
