WOW. I just recently learned about Flappy Bird, heard it was the new hot thing so I tried this game to see what the basic concept was. I guess clicking the mouse and avoiding the obstacles in sync is supposed to be entertaining. I pray for this generation.
Your game isn't remarkable in any way, the art is ripped, the animation was choppy, the mechanics were poor and offset, the pacing was non existent, there was no story, there was no introduction, there was no instruction...That's probably enough, I don't want to hurt anyone's feelings, but I would seriously consider putting a lot more work and thought into your game development regardless if you are making a knock off, at least own it and make it yours in someway. The score I gave is based on the fact that it is actually functioning and you took the time to give it to the world, which is always commendable. Thank you for your 'gift'. Next time though, it's not always the thought that counts.
