So it begins
It is great to see where this popular game series all started! This was great to play because everything you did was really casual and got you prepared for what happened next. In case nobody could figure out what was going on in the level with the upside text, it says to use "Shift". You should of course figure that out already from the title and all. Also, those pointed edges are dangerous no matter what side you touch them. I really liked the music in this and it reminded me of "The Pink Panther".
The only thing I did not like was how it seemed to take long to get into the door once you had to. You guys really have come far with the game. Every one of them gets complicated so this looks easy in comparison. It still has plenty of levels and mind puzzles to keep you on your toes to beat the level. It is amazing how much detail you can put into something with just black and white.
