Thank you very much!
I didn't want the Flappy Bird mechanic being so important in the game, so I think I'll wait for the ending of the voting stage of Ludum Dare then I'll redesign it a bit.
Thanks for playing it!
I think the Helicopter Game mechanic was quite wonderfully done, especially in the sense that it was not a complicated version. It lent itself to being a discussion on gamedev very well.
