In case anyone's wondering if this game is original, it's not, as far as I know, Artifex Mundi did this first*, they have a collection of puzzles, and I finally get the chance to just do one of my favourite ones. The design of this one is relaxing, with soothing music, soft animations and appropriate sound effects. But compared to Artifex's, these lack insight and had quantity over quality, there were times you had to guess, and the hint didn't help (I could take up any space and still form the same shape, really).
*: I recommended that you try out his/their games, they're point n'click mysteries with incredible art (best I've ever seen), audio and storylines.
