This was a delight to play through even though the battery on my cartridge is busted so I had to restart every time I turned the GBC on!
The graphics are just amazing and the music is superb. Story and characters are cute and gameplay is smooth and very effective. Impressed with all the UI effects: all the letters in the text box, the health bar/key counter. I love how Dango waddles around.
Two bugs: If I up to the locked cave without completing all the quests, there is no way to get back down and find more quests without pressing A/B/Start/Select. Also, in the first fight with the ninja in front of the scroll, I got the dumpling health boost in the middle of the fight, and then waited forever for the ninja to reappear and keep fighting. It didn't happen and instead the music kept playing with the screen locked! A/B/Start/Select again.
Despite that, this is really stellar.
