There's a bug in the opening sequence - the first character after leaving the house gets caught in place, and won't fall down to where the next cutscene happens until I randomly reached that point. Also, I was able to trigger the "hey, I got my magic" messages before that cutscene revealing the magic began. Finally, I wasn't able to jump when I was close to the jammed sprite.
This looks very heartfelt, having such a serious bug so early doesn't fill me with confidence. I'm also not one for heavy dialog sequences so early in a GB style game, but that's just a preference.
FWIW, I'm playing on a Raspberry Pi, using Raspian OS, through Chromium on the web version. Good luck.
