I liked the concept! It was quite a novel typing game.
Few things I wished:
1) I wish the visibility on the text was a bit better. I got stuck when the yellow vehicle was on the top left corner, since I couldn't figure out what to type
2) Maybe real words could be helpful instead of some fake words? At times it was hard to figure out differences between the letter D and O.
Overall, did like the concept and cool that you can do so much through typing!
