Hi! If you're referring to the 8.99 purchase version (elenastory_itch_full_windows_v1.3.zip) , no, it's not complete, and it is scheduled to be updated once a month, and once you purchase it, you will receive future updates for free with no additional cost.
If you're referring to the free demo available for download above (elenastory_itch_demo_250404.zip), it is a basically a shorter version of the purchase version, we do plan to update it eventually, but there are no immediate plans to do so anytime soon.
