I´ts a fun game, yes, great concept and good post-production, but there are two problems:
1: I found the graphics too bland (not exactly a problem,i dont even care too much about that, but try to polish the graphics a bit)
2: there is too much enemies. most of the times I get stuck in a corner of the house without any weapon because of the amount of enemies
but it´s a very good concept for a flash game
