Basics
Clicker and Client
What the free Clicker includes, and what the paid Client adds.
The two editions are separate builds, not a locked and unlocked copy of the same one. The free Clicker does not contain the Client's features in any form.
Bubbly Clicker
Free, with no account and nothing to activate. It ships the four clicker modules and nothing else:
Bubbly Client
Paid. Adds 32 more modules across Combat, Visual, Motion, Utility, and Misc, plus an account, a linked PC, and cloud-synced configuration. The clicker modules are identical in both editions.
