Well, probably better execution than the other version of this idea I've seen. I still don't get why no one (that I've seen) has tried mixing Tails's actual physics into a game like this. Maybe you could try having Tails have to fly across platforms, and then land on them before he tires out and falls. Just an idea, in case someone here wants to make a fangame out of it. Regardless, I would say its a fairly solid flappy clone, but I do wonder: "Why you aren't using actual sounds from the Genesis Sonic games?".
