I think I finally reached the 'Dolphin Jump', because I managed to have an incredible speed: 18925....It was absolutely incredible how far I reached vertically: 4520 :)
Oups...I made a typo error in my last comment.
-----------------------------------------------------
The top speed is BISTROMATIC SPEED and the second speed is HYPER DRIVE.
-----------------------------------------------------
Hierararchy of speeds I've reached so far:
1.Istromatic drive (top speed)
2.Hiper drive
3.Tachyonic speed
4.Light speed
After you crush 10 asteroids, you receive a 'BERZERKER' combo ;)
I made a small mistake in my last comment. So, beyond the "Big dolphin" constellation is "Sheep on sling", and beyond this is a large green alien face with no eyes. The associated message is "Don't panic" :)
I succeeded to win the HARD medal from the second attempt...easiest HARD medal ever woned :P

It's full of bugs...I managed to have all the pieces for the hexagonal shape, but I didn't click its center...I zoomed out and after that I zoomed in...the 6 pieces were GONE !!!
It seems that this game version is bugged...the highest rank you can get is 9.
Also lately the game is moving very poorly...and when I try to create a game, nothing happens :(
