You do not need to complete part 1 to do part 2, each part is a seperate, contained puzzle!
Therefore you could be halfway or just start part 1, go to part 2, start part 2, go to part one, etc. Each contained puzzle has its own contained solutions and DO NOT CROSS OVER.
Part 2 and 3 will be shorter just so it isn't too time consuming for people as well! You will get x1 raffle ticket, x3 glitch tokens, and 200 gold for part 2 completion as well! (Each part completed)
Part 1 has also now has EXTRA HINTS if you click on the [ hint section ] for various parts of the map!
