Hi I think the game is really great! I played 3 first levels and I have a lot of fun. However, I think the game still needs some polish. The 2nd level can be beaten in about 5 seconds using only ghost characters without doing any puzzzle. And I'm not 100% sure but I think at level 2 one of the buttons doesn't work, but this could be just me don't understand some mechanics. Overall fun experience!
