Thanks!
As I said in the previous comment, I have to tell that I did not code myself the retro TV shader (though I still tweaked the parameters).
About the part just after the first checkpoint, it is quite easy if you know how to record:
- Record going to the right a small time
- Record jumping from the bottom, to the platform on the left
- Go down without recording
- Repeat 2 ., 3., 2., 3. ... until you are out of memory, alternating between the left and right platform
Hope this helps ;)
