I seriously don't understand...
Why people are giving the controls such a hard time. If it the controls were ridiculously easy it wouldn't be much fun, now would it? This game just requires a lot of patience and really good timing. I actually liked almost every single puzzle. They all required some kind of critical thinking to complete, and a lot of them required you to be quick on your feet...errr fingers. Great physics, not too hard but at the same time really challenging, great game.
The only reason I'm offering a 9/10 instead of 10/10 is because the sound is sub-par. Annoying monster eating sound every time a block slightly moves and the music was meh.
