Update: There was an update from Itch in regards to this whole issue. You can read the full details here: https://itch.io/updates/update-on-nsfw-content

The important bit states "We are currently conducting a comprehensive audit of content to ensure we can meet the requirements of our payment processors. Pages will remain deindexed as we complete our review. Once this review is complete, we will introduce new compliance measures. For NSFW pages, this will include a new step where creators must confirm that their content is allowable under the policies of the respective payment processors linked to their account".

Turns out, Exodus did get hit in the wave of projects being unlisted from the site. You can still access the game page normally, but it can't be found on the Itch search results itself. To be cautious, we've hidden the early access version of the VN, removed the nsfw and adult tags, and disabled the ability to optionally donate. Anyone who did buy it should still have access to it. 

This should be temporary until Itch can undo the bs (hopefully). Exodus will still be in development for now until further notice. You can always get updated on the situation via X/Bsky!
