- Worth noticing
- The page lists four preset drill types, from beginner tricks to advanced mothership practice, and says each loads with the player, second tab, and bot positioned.
Field notes
The page outlines a purchase-to-install workflow: a key is delivered by email or on screen, then entered in a desktop app. Its drill list spans beginner tricks, intermediate ibras, and advanced mothership practice, with split-run practice also listed. The site says the drills position a player, second tab, and bot before practice; the checkout and gameplay sections still contain launch or video placeholders.
