So, there is this old game i played when i was much younger. You play a guy in a forest and fight off giant spiders etc. and there are no colors. everything is shadowish black. the only thing colored was the blood. and your weapon was a sword i think im not sure.

How old?

Wild guess - Forbidden Forest

Suzie.

That is definitely Forbidden Forest.

nope, everything including your character was very very dark, if not black. i can still remember those long spider legs attacking me. as i said the ony thing coloured was the blood. everything else was just black.

rough age and platform?

Limbo ?

it looked like limbo i played it like 14-15 years ago i think

so just before 2000's. I guess my stab in the dark from 1984 may have been too early :)

Which platform was it on?

The last 20 minutes of "Neverending Story" just flashed in front of my eyes. XD

Well, at least we know it was not a console game :)

Suzy?

Also there was this Dracula game... All i can remember is a toast showing up on the starting screen... and a pimp like walking guy.

Blade Warrior?
