So the basic of the game is just a coin toss, so there's not really strategy to that, just basic RNG.
The icons moving around meant I was just frantically clicking trying to hit either one of them, and sometimes I wasn't even sure which one I clicked (and didn't really care as it was still just RNG).
Any consequences for missing a click, or reward to successfully catching either icon (or bonus for hitting it in a certain amount of time) might've added something interesting to the gameplay.
The UI text blends in to the fire. At very least you should have text outlines so it's viewable on any background.
