Hi. Thank you for noticing the typo.
Regarding the page split - this is related to the page "visibility" settings. The old page has many ratings, has existed for a long time, and ranks high in itch.io's "search" and even on Google. If we make it paid again, it will be hidden, and the new page would have to build everything from scratch.
We understand that this whole key scheme is inconvenient, but we have to do it to prevent the game from getting buried on the platform.
