Hi I can't try again to use the key card in the door and do I need to get a line in the green spot right time? cause idk why is doesn't work 
Hi, I was just looking into it and managed to fix both issues.I just uploaded a new version and now it should let you try again as many times as you like. Also, yes, the line must be in the green light (Also fixed, it had a very small collider)
Feel free to try again and let me know what you think :)
Thanks for your feedback
