When I was very little, and the, I speak about, 12-15years ago. I remember playing on a PC at my aunt. This PC didn't had windows, but I don't know what other OS it had. But there was some commandline I think, because you had to give a command to get in some kind of menu/OSlikething. This was just a screen with some icons and their title's (again, I think so, don't remember very well.) And there was 1 game. It was a platformer, but I can't remember the name. What I remember: Blond(yellow) haired character. Red body(clothing, whatever). When you started the game, I think that you saw a forest and some castle's. I kinda remember a red border for some reason, maybe around that "world map?" When you died, you died the same as in Super Mario Bros, so that the character looks at you and falls down the level. In on of the first levels (or maybe the first), there was water, with a shark in it. And a platform to get you over that water. What game am I looking for?
