Utterly terrible game with serious balancing issues. First few days are nearly blind luck; restart if you need to.
Day one: buy fuel, left & right rockets, and height. To launch, drag the hedgehog down to the pause button and release. Once you clear the surface, gently steer with left/right arrow. Try and hit platforms. Those will bounce you up a little. Try to snag coins. Coin score is multiplied by a figure based on run height & duration.
Your goal is to get $400 in the first few days to buy radar 2. It lets you see ALL the platforms. From that point, you can bounce around longer & earn enough money to buy more fuel. Once you do that, more left/right rockets so you can get to more platforms faster. At this point, the game becomes ridiculously easy. Get other upgrades as your money allows. E-rocket is "nice to have", since it can shoot you back up when you risk falling down to oblivion.
Made Mars in 11 days. Good luck and don't let this game get to you.
