Did you make all of the 3d models in this game? It looks very well done! I had some trouble with moving in game. It seems that I cannot move and turn at the same time when I am running into an obstacle like a wall or table. I think it is because the character has a square collision box. If you made the collider circular I think the player would have an easier time navigating around the tables. As the game progresses I found that refill orders came out so fast that I only had time to service the side of the restaurant nearest to the refill station. Maybe you could introduce a mechanic like anger that would incentivize the player to service tables that have been waiting a longer period of time. Aside from that, you have made a very nice game!
