Okay so the concept and execution are very good, The presentation is top notch. However, In my opinion, What lets you down is the level design. As an example there were multipls examples of text appearing half on the white background(good) and half on a black level object(not as good). Also I was not always sure if i beat the level or if it just ended. Apart from that i found your game really interesting
Also, I got a little chuckle out of the blender logo killing me because that's how i feel whenever I open that complex ass program.
