Okay, I don't think I really understood what I should really do to beat this game... I tried the first level yesterday and I was like "ok, screw it, it's impossible!" but since I wanted to go straight to the end today I managed to skip the first level by just walljumping without even have to press E or Q. In the second one you don't even need to use the phone so I managed to finish it pretty easily. Maybe I'm just dumb lol
