Thank. Glad you like the graphics :)
About the issues:
1 - Yes... extremely easy, forgot to rise the HP of the dragon, it was in "test mode".
2 - Hahahaha, I didn't see that one! I used a Slider UI and forgot to remove the event system.
3 - Yes, I made the procedural texture myself, and didn't had enough time to process and make it seemless at the edges. Houses and trees I added some of them 30 - 40 minutes before the deadline, so yes... there's definitely big issues I didn't had enough time to check.
Thanks again for the feedback. Will fix everything I can for the update!
