Grand Dojo
The City’s training centre lets the duck replay all 25 exercises and train beyond level 100.
All training games
Choose any exercise from the five earlier dojos. The creator confirms that this is the same set of 25 minigames.
Higher levels
Training above level 100 takes ten times the XP per level: 1,000 instead of 100. The creator confirms no intended cap; this reference describes levels beyond 100 without assigning a maximum.
Rankings
The PC Steam branch includes training leaderboard submissions and ranking grades. This source branch does not establish current service availability or feature parity across every mobile/PC storefront.
