This game is wonderful. I absolutely love the atmosphere - and the fact that it's a genuine GBC game is incredible. Dialogue, cutscenes, customization, gameplay - this little game packs so much. Even the music brings me back to the GBA and Pokemon Emerald (since I never had a GBC), and I love it.
One glitch I did find is that I can sell items infinitely, if I keep talking to either shopkeeper after the first expedition. But other than that, this was a really amazing experience. It feels like a real, professional game haha.
