Its just shows an error screen, maybe i need to download this again
Can you show me the error message? Also, are you on PC or Mac? In any case, please try out the Web-Browser version of the game instead, it should work flawless: https://tyrving.itch.io/after-years-web-browser-version?secret=2xVhaOotNJrmXN445... (I highly recommend running the game in Chrome or Firefox - the former should work the best in terms of the overall performance.)
