Not bad
nice game with the unoriginal ragdoll idea but the doging i think it quite originall the game humoured me for a short while not a bad game.
Suggestions:
-Maybe have different falling objects instead of spikes mide add to the effect of the game Example: chairs limbs anvils pianos (GO WILD! =))
-Have levels like make it easier then make it progressivly harder i know you have done that but in my opinipon it would nice to have levels ( like a timer so you have to survive like 5 mins on this level to get to the next )
-High score board, maybe you should have ago at making on of these so people can compete it might keep people intrested in the game as a little healthy competition never hurt anyone :)
Good Luck with future games :)
