Hi! We're updating all versions. The date next to the version is related to an Itch feature. The free Android Itch version is the previous paid version. We have to reupload the other versions to maintain the "update" functionality through the Itch app—if we do this with Android, Itch will archive it as a zip, and you won't be able to install it via a mobile browser. In other words, the free Android version matches the free versions on other platforms (you can check the version in the main menu).
