Looking for a very old game

I am trying to look for a very old game but I can't really remember what is the title.

What I can remember is that it's some sort of first person game, ranged weapon (bow) if I'm not wrong. The setting is in a heavy fogged swamp, with frogs, and mushrooms scattered. The setting is so eerie that I can't finish the game when I was young.

I think that's all I can remember. With these keywords I can't really find anything similar. I really wish some kind hearted here could remember something like this.

I'm 25 this year. I believe the game was released roughly in the 90s.
