Ummm. Don't know what you were trying with the game page (https://rovshan.itch.io/noteplay3d), but the effect (to me) is that it looks like it was made by a 12 year old, which sort of sets my expectations about how well it'll work and play :-(
What is special, significant or unique about your game? Why would I want to download it rather than any of the 1000 other (no offense intended) crappy shooter games out there? What would make it worth downloading?
