Really nice submission! The gameplay is essential (in a positive way!), but yet very effective. I think you did a great job in creating something with simple mechanics that is both cohesive and fun. Furthermore, it has a lot of potential for future expansions, if you'd ever want to.
Regarding the gameplay, the dragon is very hard to control, especially as it is a game that requires precise movements in a limited time... But I guess it's the point of the whole thing ^^"
I read in your other comments that the development wasn't easy. Game jams can be pretty though, I know that, but remember that you don''t have to deliver a game at the expenses of your health. It's okay if some (or many!) ideas get discarded in the process, they could always return for the next game jam.
Overall, I think you did a fantastic job for a challenging three-days jam! Congratulations :)
