Is it me, or is this game hard as hell. I cannot get a good score at all, i barely make it 5 minutes in survival, they expect me to get through all about 50 levels? because i cant even get to level 24. This game is hard!

I am at level 40 for one, and at 32 for the rest. I love the game but I sware it makes me a little crazy. I get visual distortion from the game.
