Pretty much another flappybird clone, but if this is your first game then good job and good that you posted it!
Some criticism tho:
Maybe next time take some time and make a main menu, high-score system and some sound effects. A bit of polish makes your game better, even if it is a clone game. The things you learn making them sticks with you for when you start to make your own original titles.
Good that you made your own art but learn about pixels-per unit and make your art acordingly, it looks okay now but if you make a bigger game it would be hard to make the art fit togeather.
But TLDR:
Good start, keep at it and post your games but give them some polish. Hope to see your future games :)
