I found the game super charming and the concept is fun! I wanted to try all levels, but I thought it could have maybe an in-game tutorial to make the aim of the game clearer: is it to make all blobs touch the green square or only the red one? I think the first levels sort of misled me and then I found it difficult to progress past level 4 because I wasn't quite sure what I was trying to achieve in order to advance.
