It had potential, until I got to level 4. I get stuck if I try to even move left/right. You can't jump unless you wanna go directly into spikes, and there is no down button. I walk to the left about 5 steps, hit an invisible wall, and realize that I'm a sitting duck for the horizontal spikes. When I try to retreat, I am blocked by another invisible wall which leads to my death. Can't even get to the lower part of the level.
