[PC][2009-2014][Puzzle] A dark puzzle solving game where you have a minigame where you act as the key to solve the minigame to get solution to the next puzzle

Hi,

I have seen my brother play this game a long long time ago ( back in the days when AMD was making HD 7870 )

I can't seem to find the game at all.

It's probably an indie dark puzzle solving game. It was a fixed camera game. I don't remember if it's 2D or 3D.

I remember a scene where a guy is target practicing and you roll over the pellet jar to make the guy slip on the pellets.

I also remember there was a water level. The most vibrant thing i remember is that you act as a key to solve a minigame to get answer to the next puzzle ( i also vaguely remember that it had a cooldown? )

The game also had a step by step walkthrough on some website.

As for something technical, it didn't run on my intel igpu back then due to driver errors.

Thank you for your insight. I would love to replay this game ( as i hadn't finished it due to my brother moving out )
