For clarification:
------------------
- Levels correspond to the 5 different background themes (5 total)
- Rounds represent the boards within each Level (# varies from 5 to 10 with each Level)
- Cycles represent how many times you can go through all the levels (5 total)
For example, when you see Level 3-2 on a game board, it actually represents
Level 3, Round 2. When you start the game, you are an Explorer (Cycle 1) and
gradually get promoted to Adventurer, Excavator, Surveyor, and finally Researcher.
These Cycles can be seen by accessing Replay Any Board from the Menu button that
is visible in the game.
