After playing the game, I assume this was meant as a practice game so I will try to be helpful.
1. Good job on voice acting. It was a bit wierd hearing it after both MC and Dragon Tamer being quiet, but I know how hard it is to get multiple voice actors, so don't read to much into that.
2. I was missing the really music trough most of the game, and if you are planning to update this project I really recommend you put more music in. There are places where you can get game music for free, so I think you can't miss with it.
3. The story can be pretty inconsistent and plain at times, so if you plan to write your own scripts in the future, try looking up some creative writing tips.
4. Also try not using different art styles within a game, that road background felt really out of place. I'm not talking about story relevant art tho. The sheep drawing fit well since it was timed with the story.
I hope this was helpful and that I see some of your work in the future.
