You had requested the latest version of the Marketplace, and I sent it to you via Discord (03/12/2025). It's not something I usually do, as I've been scammed before for sending the source code outside of the store.

Purchases made on the GameMaker Marketplace remain exclusively linked to that platform.
Although the store still exists, authors are no longer allowed to upload updates there, so it is technically impossible to distribute new files to existing buyers.
Free updates exist as long as it is possible to update, as long as I am alive and as long as the store exists.
Since the GameMaker Marketplace platform disabled updates for creators, those updates can no longer be delivered through that store. The license agreement also specifies that updates are provided when possible (6.1, 7.1).
Itch.io is a separate marketplace with its own licenses and terms, so releases published here do not automatically replace purchases made on another platform.
I hope you understand and I hope this clarifies the situation.
