Game takes nice use of the usual Flappy Bird mechanics but changes the concept so that it's much more entertaining than the actual Flappy Bird (at least for me. I never saw the appeal in FB but this striked at me like a truck).
I did quite like the music and the whole concept, kept me hooked for an hour or two without even realising. The rank it shows motivated me to keep going untill I managed to suddenly "zone out" and find myself into ridiculously good run and get 26071 points in Hardcore (Rank 1). Horray!
Multiplayer addition is a nice touch that I'll definitely be giving a shot, should I have a chance. I can see all the laughter already.
(Game did indeed get a tad on my nerves during the last part I was playing but thankfully I've had practise with games like IWBTG, haha.)
Only complaint I could think of is lack of more varied obstacles/power-ups, but maybe I just didn't make it far enough to get to them? Could be.
Excellent work, looking forward for more.
