Backrooms Crawlers is an incremental dungeon crawler that normally costs $1.99. Right now it is free on itch.io, and the offer runs until October 27. It is available on Windows, macOS and Linux, so most desktop players can pick it up.
It suits players who like idle and incremental progression, where your runs gradually build on each other, and anyone curious about a Backrooms-themed take on dungeon crawling. Since it costs nothing, it is an easy one to try.
Once you claim it while the deal is live, it goes into your itch.io library and should stay there after the promotion ends. Claim it before October 27 so you don't miss it.
