Well...

...all in all it's a simple yet effective game with a lot of potential. To make it better consider adding more options and ways to wound the victim with different outcomes at the end, it would defiantly add a repetitive element to it. If you made a sequel or made a newer version and put in more levels and what I said above it could be a mega hit. Oh and it reminds me of final destination. (o.O)

A great Halloween game!
