Not a bad little game! I like the added challenge of hitting the dino.
I will say though, I wasn't able to make it very far in the game as the walls are too close together. Either the bird needs to fall faster, or the walls be moved further apart.
Also, if you hit the first wall you are soft-locked and have to reload the game.
Animations are great, love the style and the effects you have added. Overall, good job, just needs a little bit of polish.
Keep it up!
