Progress for this week:

• Added 9 new levels (total of 46 levels).
• Added a new slot type, Mirror, which duplicates an item to another slot.
• Trying out a hint system that tells the player the target balanced weight for each level to achieve 3 stars.

Planned work for next week:

• Get to 50 levels.
• Record the number of hints used in the save file.
• Display the total number of hints used on the end screen.
• Add a Settings option to clear save data.
