I recently bought chapter one (nutaku) after playing some of this demo (windows) and I noticed that there are voice clips present in the demo when first meeting the slime girl for some of here dialogue at the start that seem to be missing in the full version. Was this change intentional? I was kinda disappointed to notice they were gone.
Apart from that, great job; I loved Monster Girl Quest and I look forward to seeing more of these games.
edit: One last thing. I noticed in full screen that the tops of the letters of the sentence below the first get "cut off" and can be seen before they should be visible. No big deal, but I thought I might as well let you know if/when you see this and maybe didn't know. :)
