No, it's not stopping creativity, it stops the laziness and shortcuts, please beat the level the way it made with. And if the movement is not the best sorry this is my problem, I don't have a lot of experience in FPS movement so I might corrupt things but I hope you like the game.
It's not bad at all! But it might be better, Learn more in C# language and in unity. Make a lot of games to upgrade your skills. and be proud of yourself. :)
In fact, the settings are not working in the main menu but it's working in the levels... And also, this is my very first game jam ever, so I did my best and thank you for your feedback!
