Dragon Flame Interesting
I like the casual music in the background. It's like walking your dog in the park only with people screaming. Its a nice game, but it could use a little more. Someone once made something similar, but that was before I got into this criticism thing so I don't even know who. Basically there are only a few things to make this game better:
1) Upgrades. An RPG factor makes every game better. Consider killed units dropping money and making upgrades that increase the duration of that fire breath ability, your dragon's speed, his health, and perhaps add a few other things into the game.
2) Something more interesting than the same thing over and over. I didn't go too far into the game, but from what I saw in the first few levels, it is the same scenery recycled. Consider either siege battles, or change in scenery.
3) Rework the controls. I found it annoying to have my dragon follow the cursor where I want to shoot, only to walk into an arrow. I suggest WASD to move and the mouse to shoot.
