I did try the web version and sadly I didn't make it even through the tutorial level because I did not understand how to get across the single dark tile after the fire pits - I tried switching this and that and collecting this and that and died a few times; I tried finding out if your game page has something helpful on it but if it does I didn't find it.
I like the premise of the game, handling two worlds is always fun puzzle concept. Since I did not come far I am not sure if your game has that special spark.
I found the movement slow, and it did not take my input when I felt it should. I can see this game being fun when it runs smoothly though.
