Wow, this is really fun! I like how you get a chance to get familiar with the mechanics before things start getting thrown out of windows. my only problems would be that the side to side movement feels a bit rough and having a restart level button on the game over screen would be handy for restarting the level faster. That is, assuming you didn't take out the restart button knowing that people would play the game for hours on end, lol.
Also, the way the game ends with a bang sound and then the music gets really quite is just perfect.
