Hello! Thanks for the feedback!
About the error:
I just downloaded the game and debugged the code. Everything works as it should, and there are also no errors in the direction of water.
Perhaps you misunderstood the management. The project page describes in detail how to manage the club.
Management:
Teaching the cube to walk - W, A, S, D;
We tell the cube that it's time to go – Enter;
Restart the level and tell the cube to forget everything - R.
There is also source code in the project files <Game_Code.cpp > . If you are interested, you can try to "mess around" with him somehow.
I warn you that the code looks terrible.
