Nicely done. I like how the first dino points to the sky when launched and the concept of multiple launches.
I managed once to bounce on multiple shrooms and headed straight to space! It would have been nice to have more of those moments instead of the more frustrating ones like hitting the balloons from the bottom and get smashed back into the ground.
Oh, and the game runs fine on linux using mono, I didn't check it earlier because it was marked as windows only, but I tried and it worked :)
