I believe it’s fair that the new version is available as a paid release. Creating these high-quality renderings takes a lot of time and effort, and I’ve also invested in better hardware to give you the best possible experience. By supporting the project, you’re not just buying a game, you’re helping me continue improving and creating even more exciting content for you to enjoy. Thank you for being part of this journey!
