Extremely impressive! It took me awhile to figure out a tactic of growing my word size. I ended up in a rhythm of making a word with how ever many spaces I had unlocked, then adding an s to the end, then forming a new word of the new length. Once I got that down, became a lot more manageable. I was also really surprised to see just how many words it registered.
Art is really well done, and overall polish and execution is really great.
