Nice! I haven't seen this add-and-destroy blocks mechanism before in a block slider. I think it's unique, and fairly well implemented.
The screen shake on collisions is cheesy and distracting, take it away. The levels are generally well designed, with an appropriate level of challenge variation so far (up to 36). Well done!
I really thought that the answer to the last challenge would be that Greek Socrates reached the same conclusion as Socrates Jones, ie was awarded the prize for the same non-answer
Can you try it again? We have tried to fix it in version 1.4 (you can see the version in the top right corner while loading).
