It would be cool to see this developed a bit more. Like- add some variety or randomness to attacks. Make dragons move a bit. Also- limit the gameplay area to the screen- dragons, as well as the player can leave the screen area with no problem.

The boss has one attack, a spin flamethrower that doesnt stops, every fight is just a sidestep shooting, also, sometimes the dragon spawns outside the screen, So you cant see whats happening.

Adding simple things to the game like a :"Reload time" to the boss, Changing the spin direction , More patterns, Changing the color of the dragon after each respawn , and making that the dragon spawn inside the Screen will make the game way better

it has a bug
