I can't see myself purchasing these games without achievements.

It would be great to have Steam achievements and Steam Trading Cards!

I remember when mobile games had a good story in it, like Brothers in Arms 2 or Gangster.

I love the idea and design of this game. When I noticed that optical illusions were part of "solving puzzles", I though I was gonna have a nice brain teaser experience. Was extremely disappointed. I Get why the game has very positive reviews, it's an enjoyable experience, but I was expecting a puzzle game. This game instead is extremely linear and easy without much thinking required to complete the levels. If you check my total gameplay time, it's 2.,8 hours. That's what took to complete the whole game...

Playing the box level and it doesn't seem super complicated, so I got to the yellow side and now all the doors are closed and nothing happens. I youtube'd the level and it looks like the left wall is supposed to swing around and reveal a handle to turn, but nothing happens? I restarted the level and same thing. I'm stuck and confused on what to do?...
