GameOverScript/MinimapCamera

Hello everyone, I'm an absolut beginner in unity and followed along some tutorials. now i just made my first mini-game, yeah. 1) i wanted to upload it, but i would have to upload the entire folder (96MB) and didn't find where i can do so or share my project otherwise (simple files are no problem) 2) the game overall is working, start-screne, levels, end-screne are all good, except those issues: the game-over does trigger when my cube hits the ground even though it's NOT tagged as such. therefor the reload is not enabled. but if i hit the obstacles it does stop (recognizing the EndGame-Script). i reeeeaaaly looked it through over and over again, but cannot find the mistake. can anyone please help me?? 3) (minor concern) i made a minimap and it's working good, except the quality is pretty bad
