Thank you for your comment!
This was my first time creating a multiplayer game. While implementation was easy using Codex, there were still many areas for improvement in the game design.
I decided against including a chat function. I don't think that was necessarily a mistake, but even so, I restricted communication too much. I tried to avoid the "worst-case scenario" by making the hint function available multiple times, but it wasn't a very good solution.
Thank you for your helpful feedback. I want to create a game that players will enjoy. I want to improve my skills so that I can consider various scenarios to avoid causing any unpleasant experiences.
