No, but there are instructions in the description. You probably have the installation blocked by Google Play Protect. To proceed with the installation, click “More details” and “Install anyway.” This is because the game is built for older versions of Android to transfer saves between updates automatically. Also, there may be a possibility that the process of downloading the installation file from the itch io servers failed. Try downloading the game from the free public post with the game release on Patreon. There are several links to different file-sharing sites there. You can choose any you like.
