This is a very good idea for a start. For my i would add mabye a hero to go through sorta final fantasy styled. I like the graphics but I think the mountains could use more detail. I would also like this for mabye an FPS game. I gice it a 2/5 for now but once it turns into a game you can play i would probably rate this much higher. but just for the map 4/5.
I don't meean to dissapoint but it is really boring. You should add some music to this a bit. also you could update the graphics and gameplay so it could be faster.
After beating the game on insane in my first run through i noticed I didn't get the Dragon rage badge. so in jus beat the game in 5 minutes on easy and for all my troubles i still didn't have it. :(
