Thanks for your feedback!
You can actually disconnect using the spacebar, but I agree that if you don't know it, with the zoom, you risk not seeing your target anymore... Definitely something easy to fix in the future ^^
Regarding the delay, it might come from the fact that you only move when your have a direct line of sight to your target, and that maybe wasn't as clear as I thought! Another things to fix :)
Thanks for playing!
