I'd like this better if it wasn't tied to Flappy Bird. If it were just a more generic kit for fun. I definitely like the idea of using it for workshops for kids to get into tech, etc. But blatantly Flappy Bird? Sours it a little for me.
Now I still play sometimes, almost as a way of relaxing. Once you get the hang of it, it's easy, but you still have to pay attention and you can still get tripped up. I'd say it's a very rewarding game.
Just yesterday I finally beat my friend's score of 171 with 203.
