Great work, just a few suggestions
It was really cool. The suicide choosing games are a little too commonly found on Newgrounds, so maybe you could make it different from the others, you know, you could make it so that you could aim the gun or knife at a certain spot on his body and it would kill him a different way. Also, add more options and a few more SFX. It might be a lot of work, but believe me, to get something great going, you need to put a lot of work in.
