A very well done game! Have to say I'm personally not that much into side-scrollers, and never played that much the velociraptor game in Chrome. But, I enjoyed playing your game thousand times more that the Chrome game.
I found the animations very very fluid, I really liked the animation at the start of the gameplay (it made me feel a bit sad, but it is the kind of dark humour I like), and from animation point of view it's perfect.
I had an issue with the main menu screen, as the Logo Images were on top of the menu and I could not see the contents of the menu. At the end I pressed enter or clicked around and the game started (but I could not change the music settings). Maybe it's just my computer but wanted to let you know. Overall, the UI elements design is awesome.
The music and sounds match the entire game and is consistent. The gameplay, which to me is the core of games, is very original. Never expected someone would see the velociraptor as a projected shadow. I liked the change size feature and that depending on the size you jump more or less high. Also, the meteorites make the game very dynamic as you have to check both the projection and the 3D.
At the end, I could make until a very sad 350 points of score. The new elements make the game quite more difficult that the original velociraptor. I had tons of fun playing your game.
Suggestion for improvement: add a story mode in addition to free running mode. This story mode would focus on passing levels (reaching certain score for example) and having story between levels. You can even add boss fight levels. You already created a very funny animation and story at the beginning, I think it would be just build on top of that.
