Cute, but limited
Interesting concept with angles. The idea being to destroy the stationary goblins with a stationary dragon that breathese bounceable fire, as if it were a rubber pellet. With obstacles, and control over angle and speed, you have to hit all the goblins.
The game is cute, but really slow. It might be worth checking out on a slow day just for the novelty.
