Very cool game once I got the hang of it. I had a slow run, but I found a funny exploit and played around with it a lot. :D
If you jump against a wall and keep the direction button pressed, you slowly slide down the wall. So far, so good, all as expected. :D But then, you can keep the up button pressed and release the direction button. Now the slide still continues. Press the opposite direction button while keeping the up button pressed. Now you fly through the air and slowly slide down while flying. Press left or right while keeping the up button pressed. :D
