Any advice for advertising this game and feedback?

Hello, I made this game in around 1 month~ as a passion project and Im looking to maybe monetize it. ITs a tower defense game, a genre that has seen success on roblox recently. Could you guys give me any advice on how to maybe make this game popular, or any steps i should do to make the game better before hand. I also have a bit of robux/ad credit to advertise it however Im unsure about how to use it.
Heres the game (best played on pc): (7) TOWER ASSAULT - Roblox
