I was really confused what to at level 2 with the button because it said even and I thought it had to do with my ghost's number? but it didnt do anything? I also can't really see how the #2 ghost is "skinny" and it confused me a little at first. Other than that though I think the concept is pretty cool how you have to use multiple forms to progress through the level while having to deal with the obstacles and making sure you use each ghost strategically.
