First impression of this game was kind of "What is the point of it?". After reading comments, and realizing its a kind of experiment I would say it is a nice start but it needs improvement in many ways if you would like to add it to later games. And I'd like to add that you can lose (on playing the first time, and not reading effects :) ) Cube can outblock you.
Hi Gregory! Though I'm not done with the game yet, but in the elite training zone Concatenation section where you teach how to add space there is a surplus " at the end of the line, not sure it is intended or not (I think it's on page 5)
