Stellar Echoes is our initial beta release in the EA period, mainly showing the construction of spaceships, materials, lights and other performance effects under the HDRP rendering pipeline, and tested the frame rate limit of the HDRP rendering pipeline in simple planet mission mode, however there may be some compatibility issues, say "sorry" to everyone. Recently, a very bad thing happened, after thinking about it for a long time, I decided to tell you that in July 2023, all the game data of the HDRP version was destroyed and deleted, it was impossible to retrieve, which directly led to the HDRP version not continuing to update, we also brought a lot of difficulties to the development of SE's URP version. Seeing that friends all over the world are still continuing to buy our games. I have to say bad news, please be cautious when buying this version, due to this bad news means that I need to spend more time remastering. At this time I feel the same heavy as you guys.
