Thnx a lot for your comment and thank you for taking the time and testing our game, as you pointed out I was using an AZERTY keyboard and forgot to change the key bindings n and for the pause menu I was pretty much lost in unity prefab system and this is the first time using unity for me ( last was 2013 maybe ) I'm a ue4 dev myself and wanted to test unity wich sincerely I'm impressed at how simple yet it became, anyway i fixed it and updated
