Just not my jam
I was turned off by obtrusive shaderFX (which are cool, but annoying AF) and the need for timing that is really just guessing and checking.
Very nicely done for 3 days of work, but I'm not impressed with your take on the theme.
Also, there's nothing really sticky about Sam, he just moves until he hits a wall, there's clearly no gravity or anything that would require him to stick (at least, so far)
