"Kept me hooked until the very end"
I think what made this game hold me so well was the progressiveness of the difficulty. As new things are introduced, they become a new challenge to keep in mind. However, not ever room after the introduction of a new element will contain it and I feel that this is a good way to keep from over stimulating all at once. The player gets to refresh their mind on other details and also gets a chance to maybe find an easier puzzle to contend with which raises morale. The art style is very easy to digest and without explanation, you can easily figure out what a certain block entails. The tranquil music that plays is also engaging in the sense that your mind can process right alongside it. I had no clue how many levels there were, but I was determined to go as far as I could during the time I had available, I now will wait for the next levels to come and to see what new blocks they will hold.
