1st of all - Add some background music to the intro and the Game Over screen.
Also, I don't get the rules of this game.
I clicked on the rockets all the time, I thought I went higher, but after 2 mins, the game over screen pop out.
So, yeah.
The game rules are not clear, the graphics are OK, and you need to add some music.
Look at your altitude, with the little bear icon, when that hits the bottom, you fall out of the sky. Adding BG music to the intro makes it hard to hear the voice. There is already too much music in the game. Main menu, store, 5 songs total for the levels, adding any more songs would increase the file size to an unacceptable limit.
Okay game, not exactly horrible. It does consist of a lot of repetition, though. But anyway, I love the animation but the actual gameplay needs a bit of work. I find myself doing the same thing over and over, but it was nice to see a twist on "launching" games. I do wish I could see more of the screen.
It's a good variation of the usual launcher games, but it lacks control. I don't like that the so called boost only is used to control the position on the screen and had effect on velocity or height. Also there are too many big objects crammed together on the screen.
It's kinda like what @arthurghostly said.
Too many objects going in your face, and you can't have any possible way on knowing when, or what is coming up.
But it's a good visual game, and is fun enough to play for a while.
a good thing to pass time if you dont have nothing to do
