Very original gameplay. I somewhat got addicted to this game despite some flaws that have been pointed out in other comments.
-Patterns should only count if you participate in. So you can't just get patterns by staying idle.
-Need more patterns. Maybe 'prestige patterns' that unlock after you've reached 100%. Plenty of possibilities there. Maybe also some way for users to create additional patterns.
-Need more variety on the word list so people have different words
-People shouldn't be allowed to write words from there list in a sentence or parts of the word like "say elephant" or "say ele-phant".
-There should be a way to reset the word list once your done or add some bonus words
-There should be some reward (a few miles, or a joker to unlock a level you don't have yet) when you help people do patterns you have already completed.
- Waiting for levels is just plain annoying and should be removed.
