It is a nice simple game with a lot to it. The art is simple, but occasionally a bit too simple. Everything in the background is this darkish red, but there is no difference in use between walls and background art. Making it seem that certain background art are actually walls.
In one of the levels if you stand near a corner fighting a guard then a leaf will cover your entire screen obscuring any visibility.
The wrecking ball has a nice big heft to it when thrown, but personally I prefer to throw the ball in the direction of my mouse over the direction of my keyboards.
As for the first level when you break out. You can immediately walk upwards through your exit, but it doesn't do anything. Perhaps best to just cover it up so the player doesn't get confused in walking back.
