This is a really awesome concept, and has a great amount of potential! There is one thing that I think would make the experience a lot more user friendly though. It might be just me but the mechanic felt kinda difficult to understand at first. On the first mushroom level I didn't understand why I wasn't turning into a pile of mush on the ground like I did with the skeleton. The mechanic makes sense to me now, but I think maybe like icons showing who has what ability above their heads would make it easier to understand. With that change and maybe a few bug fixes, this could be polished up into a really solid puzzle game. Great entry!
