Thank you all, for your feedback!
I will deprecate this project to keep the original state of the Game Jam Submission and continue to develop the Game in this Project: "https://grimbel2615.itch.io/rift-train-wrecksite-defense". Where I already fixed some of the mentioned Bugs.- The Issue with the Turrets not hitting is mostly Fixed.
- The Problem that the Setting wont Work is Fixed.
- You are now able to see your remaining Tokens.
- The Problem that the Enemies wont damage the Door (which made Losing impossible) is Fixed.
And I want to add a lot more features, that I didn't had the time to Implement while the Jam.
