Yeah, I kind of though that this game would be a bit difficult and complex for some. The diffculty ramp at level 3 is pretty steep, but for completing level 3: you're going to have to go to the right because in level 4 there's a switch you need to hit. And if you mean the spikes at the top of the screen: just remeber where they are and jump over them.
Anyways thanks for playing! And yes I will check out your game! :)
