Simple and quick game. I played it a few times and was able to get a third undesired item in the dragon's list.
Is there an end state? Other than the dragon breathing fire, I wasn't sure if I was making progress because there isn't any other tangible or clear feedback for the player to gauge how they're doing (such as a score or a timer). As others have said, there also isn't a lot of clarity for when the dragon will spew fire, and I wasn't sure how to prevent it from doing so.
Nice artwork, good audio. Some polish on the UX would elevate the whole game.
