Well, Game Development -> Get Feedback would seem like a good place to start looking for testers.

Once you’re feeling confident in your product you could open the floodgates and add it on mmorpg dot com. Just a make sure you have 2 big buckets ready before you do so: One for tears and one for vomit.

On the other hand, a game being an “MMORPG” is an incredibly ambitious statement. Sights unseen I would question if you have even the infrastructure and enough players to rightfully call it massively multiplayer online RPG. Maybe just settle for “multiplayer online RPG” or “online RPG” for now?

Other than that…

• Your tag situation seem fine - which is always a big relieve. :)
• You should add capitalization where needed and lose the typos as well as exclamation marks. When you’re done with that, read some descriptions of other games to see where your text might need touching up.
• Mayor publications always go for the eye candy. I’m sure you put a decent amount of effort into your logo on top of the page, but it doesn’t even have any noticeable relation to the actual game and it has a mismatching background color. Your first screenshot shows artwork of a redheaded girl. You could put the game’s title in the middle, her on the left, and a tastefully drawn male character on the right facing her (and the title).
• The background image you chose is not cut out to be a background image - less so for a game (or a game with that art style in particular).
• You current color scheme is the default itch.io color scheme. It will work well with easing regular itch.io users into the page, but it clashes with the colors you used in the images I described above. Either you keep that color scheme in mind when designing your new images or you should look into finding a color scheme that suits the images you will create. Preferably something that goes with the earth tones of your game’s borders.
• Currently, your profile page “needs to be reviewed by a moderator”. I don’t know if that shows up when you view that page from your own account, but it’s less than ideal for when you make an announcement - of any kind.

That’s all that comes to mind right now. I hope it helps.
