Hi, ty for your reply, well it's kinda strange the behavior that you described to me (I didn't have any problem while loading or playing the game). Anyways what i think happened is that u pressed right shift so u entered the debug mode (and there u see all the collesions and the objects in the screen). While compiling the game i forgot to turn it off, so if this does happen again just press the key again and it will hide. For the red thing I made it to show up when u are in a level/gate that's not unlocked, the levels that are unlocked are green, yellow for those unlocked but not completed and red for those locked.
Sry for taking u this much time, thank you again for letting me know See you next time 😁😁😁
