Your guess is correct. My computer is a quite old one and the latency prevents fulfilling the challenges. I managed to try in a faster one and problem is gone.
Nice game, by the way.
Ah the game is made using Unreal Engine 4, maybe I'll fine tricks to really get the game running on much older hardware, but no guarantees.
No worries. My computer is some 9 years old anyway, so I should get a new one.
Thanks for your answers
