If I Sponsor My Game With 30k Robux Will I return my investment

It doesn’t seem like your game is monetized that well so I don’t think you’d get your 30k back. Also the UI isn’t very appealing. If your goal isn’t to make money with your investment but build a community as you said, you want a game that stands out against its competitors and is fun. I looked at it for a few minutes, and I didn’t get a great feel for the game as I wasn’t there long, but I got Arsenal vibes from it. You want to give people a reason to play your game instead of one like Arsenal and there didn’t really seem to be one. There isn’t a lot of content and Arsenal’s visuals are more appealing. I’d also suggest using some different sounds for your weapons. CSGO’s gun sounds are pretty well known and hearing sounds from a different game in yours might be a turn off for some players that recognize those sounds. I’d try looking for already uploaded gun sounds on roblox and messing with sound properties and effects with roblox to get something you like.
