bruh, firstly there was not anything hard or challenging, just a simple nice game, and if you say it is confusing then it is not his fault that you did not understand the game, he literally explains everything with texts on the walls. And the sniper bullet should not be visible at all, because it is sniper and the bullet is too fast duh. but i agree with the part where you say "enemies can walk and shoot through walls". well he only had one week, why do you criticize the game like so, not everything has to be perfect
