Hello! Thank you a lot for your feedback. Here's the answer at each point :
- the Ui is only temporary, it's already planned to change the lobby code color
- there are a lot of bugs with the games like being stuck if you go back to menu. It will be fixed
- Later you are going to be like real ghost and not collide with everything
- To pickup objects it's right click on an object it is written in the tutorial on the main menu
- We're planning to add the possibility for the players to chose who is hider and who is seeker. For now it's only random, you just didn't have chance.
Thank you.
