I love this game, can play it for hours and not get bored.
Only thing that I would add is having an option in settings for tethered users, which will make levels generate that the cable doesn't get tangled. For example when I played yesterday I was going right for about 3 quarters of the level and at the end my cable was so tangled up I thought it will break, so try making a script that will balance how long you travel left and right.
