I'm glad you liked it!
If by always starting at begining you mean that start tile never changes is location I did consider that. It felt too repetitive as I could always go exactly the same path all the time with very little incemental change for all levels. Then I thought it could change every 10 levels or so but ended up with current system. It felt beter even though not by much.
I should come up with more interesting tiles and effect for update.
