Alright mate, I played bunch myself and developed over 50 projects. It's not a competition nor a brag, but understanding the concept of it all doesn't mean it was "too easy". The way you wrote your comment meant as if you played this like it was a simple walking simulator, which is why I commented to clarify, maybe the game was bugged for me. The smoke part I saw and it was obvious, but no way did I see any numbers or arrows or anything alike.
I will try and record this to prove my point about the game. Hope I am wrong and it truly is the case of "unattantiveness".
