It was really hard for me at the beginning too but I played it 2 times a day and practiced on aiming the mushrooms and birds (I suggested 2 because it gets too much for me after 2 tries). It just takes some getting used to and I believe you can beat the high score in 5 days the most. And once you passed the first level, the second one will give you no trouble at all because it's pretty much the same and I got the high score on the first try. So don't feel hopeless
