Hi, thank you for feedback.
There is not too much content, just 3 levels, and if it will be too easy the game will end in several minutes.
But yes the game is too hard, it is true, I got to do something with it.
I tried two ways, it looks very strange and it will completely ruin current gameplay.
But yes, I need to make bigger distance between obstacles and also I got to make lower prices for powerups and give 3 powerups of each type instead of one at start.
With powerups, the game became very easy.
