Great game! The only improvement I could think of was to add some kind of signal for low health.. maybe the screen turning progressively red or something..
For the achievement #133 I just searched a picture of an ameriican keyboard and figured the "happy face" myself... it was ç= for me... and obviously you have to make this face: :)
I love how this game is quite different from the first, not really an improvement, just different... this way the first chapter is still an amazing game and every chapter has its own peculiarity. 5/5
