If the game was not a hangout game, and just like a little game people can play but it is small, I would donate, if it had more stuff. I donate to games that I know the owner will maintain and grow, also if it is fun and I think it could be successful. You could make the chairs less blocky and make a roleplay game or something like that.
No offence to the owner if I offend you, I am just trying to give you advice to make it better.
Here is a link to a video that can help you decide what type of game you want to make it more like. It should help decide if you choose to change it to more of a game with a hangout or something like that.
This is a group I own, it is fairly new, but it is something I would donate to because it is a good idea and I think it will be successful.
Please dont copy the group, as it is just an example. If you want to see some other examples, you can look at my profile (on roblox, not devforum) and see the other groups I have recently started to help you get any ideas, please do not copy any of them though.
