This is more so a way to “advertise/market” it outside of running basic ads/sponsorship.
I’m not quite sure it will work with your specific game but it may be worth a shot to explain it, with a lot of anime based games, they run partnerships on discord. I’m assuming you already have a discord in place for the game, and could possibly try to get partnerships with other discord servers of the similar game type. It may be a bit hard, since I personally don’t know any other partnership servers then anime games haha, I’d give you links if I did but don’t really have any off the top of my head. If you’re wondering what partnerships are basically you put a little blurb of info about your game, include some video/images/sneak peaks etc.
A lot of what people said above is really good as well, I’d possibly run a paid beta/paid alpha, or even maybe free just to see how it goes, maybe you’ve already done this. Also a tip keep some content unreleased, but basically content which could’ve been released right on launch but you don’t release it, it’ll help with load management in the long run if you run into bug/glitchs etc issues.
You can also try to find investors possibly, I realize you have about 55k you’re willing to spend, but if you aren’t afraid to give up a bit of profits you can try to recruit potential investors maybe offering set values, rather then percents. But I would go against this since you already have funds and don’t really need to give up profits. About the weekend/weekday, weekends are probably a bit better, Friday/Saturday, but it also depends on your audience that the game is put towards sometimes a weekday release may be better. But also keep an eye out for big titles releasing in the near future Loomion Legacy is supposed to release on July 20th, along with another game Shinobi Story is releasing this month I think, so I’d try to avoid running big sponsor/ads when other new games drop.
Youtubers are another huge way to market games, if you happen to get some potential Roblox youtubers interested in the game I’m sure they wouldn’t mind making a video, don’t really have any off the top of my head but look for smaller ones obviously then massive ones as it’s harder to reach out to them.
As others have already covered don’t spend all your robux at once, if you have any questions feel free to reply or message. The game also interests me so if you wouldn’t mind could you reply or dm with a discord link/roblox game link.
