Marshmallow: space travel

I like the game, and the old pixel style art. The UI is decent. There are many problems though. Firstly, the fps is very low, i.e there is lot of lag. Another thing i noticed is that whenever you jump on a planet, there is a large circle, the place where if we hit that, we die and lose. I feel it is not even needed and destroys the clarity of the game. Without that, the game will feel much better. Also, whenever jumping from one planet to another, the fps drops drastically, well the fps is aldready pretty low anyway. So please fix this, it should not happen in a game with such simple graphics. Also, once we die and game over, the button to go back to menu does not work. Please fix that, its highly irritating. And yeah, thats all i wanted to say. I recommend you add some kind of enemy that will come, so we must be quick at jumping to the planets, and add powerups, ability to destroy enemy, powerup to make urself invincible for some time, and other cool things.
