Update: When I finish my current french and pychology classes I will have free time and work on this.
I've been thinking about this game, and I had some cool ideas for what I am going to do. So, the bartender hands are going to be ragdoll based, you will move the with WASD, IJKL. Rotate them with QE, UO. And grab with Shift,c and Space, N.
So, my other idea was this. What if you made it flair/music based?
So, the flair part is, the numbers bar would have tricks that you can unlock for money, which you earn by selling drinks/getting tips.
The music part is, there would be a radio under the table which you can select whatever the BGM is. The radio also displays the songs waveform. If you press buttons to the beat of the song, you get extra points.
In addition to that I would try to make it a lot polished and have clean art. I think it could be a cool steam game. And my first real game lol, cause my other stuff is just demos.
