I think I finished the game, I get out with all the cash, but there was nothing to escape. Maybe a car waiting for the player would have been cool at the end to really finish it.
I liked the art of the character. But I think you could have work a little bit more on the level design, to make it more interesting than just straight levels with two stairs at the end and at the beginning of it. And make it clearer that the stairs where stairs, cause it took me a long time to understand it.
A little more SFX would have been nice too.
There's a lot to do to improve it and make it a great enjoyable experience :) But it's a good start :)
