That's a very cool concept who reverse the usual gravity-games! Good using of the themes and a well managed physic. The camera can be improved, but it's didn't bother me more than that ;)

Fun idea, but a little bit half-baked.
I liked how everything can interact with everything. What really needs improvement is the camera - the player sees less in the direction of their movement, making it unnecessarily hard to dodge stuff, I'd do the exact opposite - a camera leaning in the direction of the movement.
Still, good job!

Some concepts I liked in order of greatest importance to least importance:

* I liked how the controls were pretty simple. I just had to use a mouse to drag the planet and that was it. I did not even have to use my keyboard.

* I liked the soundtracks. They did not sound repetitive and they sounded nice. Also, the soundtracks fits the mood and feel of the game. The soundtracks made me feel calm while playing the game.

* I liked how interesting it was to manipulate the rockets to crash. Doing this made me feel clever, and there were tons of ways Icould make the rockets crash which I found immersive. I particularly liked crashing one rocket into another rocket, but crashing rockets into rocks were fine too.

Some concepts I did not like in order of most important to least important:

* I did not like how the instructions were presented. Though I liked the fact that the instructions were told in the game, I did not like that the instructions were just told by a big chunk of text. When I read the big chunk of text and started playing, I kind of forgot the instructions (I remembered using the mouse to move but I did not remember how to lure rockets towards me).

* I did not like the fact that when the player dies, the player has to go back to the main menu again to play. I did like this when I first started playing, as I forgot the instructions, but I did not like it after the first time. It felt repetitive to go back and forth between the menus.

* I did not like the camera of the game. Since the camera was too zoomed in, I could not see rockets from far away and I sometimes was afraid to move in fear of getting hit by a rocket that I saw at the very last second before my death.

That's a pretty cool way of having the player be the weapon. Is it possible to destroy the other planets?

I love making ships collision between them xD. Good game, maybe it would be better with the position of the covers changing in order to make the gameplay more dynamic. Really fun idea.

Funny and creative.
