no? If you don't already have the option to update on the bottom right corner ( I assume you're using the Itch.io app and not webpage) you go to the cog next to launch button to manage the game and if it says v0.1.2.2 as your main file to manage you'll want to either A. Uninstall it than install the new update or B. install v0.1.2.3 ( the new update) which should overwrite the old update and keep your save files without having to transfer them
