I didn't expect much from the theme and the screenshots, but this is really a brilliant platformer! Just right away awesome!!
However, with one restriction: The last year/episode stopped me playing because here the difficulty requires very often a higher precision than your controls actually can offer. By which I mean to say: To demand precision reactions from your player, you must offer high precision input. And the treadmills, just as an example, reduce the precision at which the player object responds to the space bar press drastically.
Still, it takes time to get there and all previous episodes are well crafted and got me smile quite often!
Great job!! Hope this feedback helps somewhat! :-)
