Hello Guys, How Can I Get my game popular

Hi,  Use basic marketing , promote it on YouTube or other networks, Improve the thumbnails and the central idea of your game to attract more attention.

mostly from what vilictus said, a good game has good marketing. try to improve on thumbnail design if you cant theres always designers you can hire if you have the money

make the title, and description more eye catching (seriously wtf does APS mean)

also polish to the main game, add a sprinting animation plus better reload animations, also disable shiftlock since your game has sprinting and is in first person anyway

disabling reseting and a custom death sound would also be good, remove proning and maybe even crouching (your game feels fast pace so crouching and proning in a fast paced game feels weird) add a custom crosshair and make looking left and right with the Q and E key a hold instead of a toggle, literally makes no sense and last but not least lower down that damn jump power

gave you a big to-do list and theres even more you can add if your seriously commited to making this game good

If you have money you can get robux and put up an advertisment on the roblox page, you can aslo advertise it on ther social media platforms. you can even hire someone to help you code and design some more advanced stuff and hiring them wuld be worth it as you would ge some money back afterwords (robux)
