Once I figured out how to play properly, I really enjoyed the experience! The baby dragon is super cute, and the sheer variety of final dragons is astounding! It takes the idea of different final forms and knocks it out of the park.
However, there were a few readability problems in the game that made progressing impossible until they were worked through. At first, I thought the game had softlocked, because I couldn't do anything to progress. The Hunger Meter going down means he's fed, and 100% means he's very hungry. The meters are not totally consistent, because 100% Mood is a good thing.
This would be a nitpick normally, but when mood is low, you can't feed the dragon, so it looked to me like 100% hunger meant he was too full to eat anymore. This false understanding caused me to be unable to progress.
And it would have been a shame if I left it at that, because the game is so lovely to play through!
