Wow it's a tough game. I understand there's a level of skill to be acquired. I don't play smartphone games so not that familiar with the technique. Only criticism is that appears to be no way to dive faster than gravity allows .Some pipes are therefore too close together. This isn't a title you can play over ten minutes. Otherwise I'm, impressed with the on-screen presentation.
I have only played the original Flappy Bird 2 or 3 times myself, just to compare difficulty, and in my opinion, the original is still much harder than Flappy McFur. The main difference between the two is that Flappy McFur's movement is far more predictable that Flappy Bird's. We figured a disembodied Jaguar head would fall more like a stone instead of the almost feather floating randomness of a bird.
It was interesting during play testing to see how well people did the first time. Nearly everyone would hit the first pipe or ground. After that though, some people would only get through the first pipe while others would breeze through 5-10 pipes. It also depends on the play mode as well, as there is a tapping timing strategy for each one. We tweeked spacing between pipes and collision boxes a ton during play testing to try to get the right balance of at least some progression every round for every player and enough challenge that someone can't beat it in 10 - 20 minutes.
With our few play testers, after a few minutes of play on a specific play mode, they all were eventually passing a handfull of pipes each time. It does take a bit more time to refine the technique though, and to learn how to anticipate certain situations.
A small tip for anyone who wants the shortest route to the end. The fastest way to the finish line is Flyer mode. And a few of our play testers consider this mode the easiest to learn as well.
I promise, the game is beatable. Thank you for the feedback and good luck
