Game's based way too much on luck. You try to jump over something then fall into a gap. Then you realize you should have hit it to slow you down. Windows come out of nowhere and almost every time you'll fail to jump into one.
Too unrealistic. If as much as a single spec of debris flies towards the building or just nudges it, you lose. The lose sound is annoying. You can click the boom button more than once, but it may glitch the dynamite and count it over the line.
