Could you please try to be more specific? I`m sure none of us here are a ``vaguely described games`` database. Thanks.

I can not be specific because I have no idea. As far as I can remember it is a side scroller and I have no idea what the objective was. Mostly to not die. The 3 characters are the playable ones, don't even know if their was enemy characters. I tried googling all my specific memories and could not find stuff, so I do not expect it to be easy to figure it out. It is at least 15 years ago that these memories come from a specific game that I did not play that much.

So, you try not to die. That's pretty much every game out there.

Lost Vikings is the only thing that makes sense to me. But it has been mentioned already ..

I have also thought of the same... :P

Its probably not a famous game like the lost vikings. Oh well I can not remember anything else about the game.

Your description kinda reminds me of Toejam and Earl, though it only has two characters, and I'm still not sure how many eyes does the yellow guy have.

Just one eye. My description is really bad :P. I just remember playing this game and that it was fun :).

With the exception of the PS3 masterpiece Flower.

Sega Saturn or Genesis, definitely Trine.

Ok, give us some more information...

Is a single player o 2 player game?

At which point you can choose the playable character (at the beginning of the game, during each stage, at any moment?)

do the guys shoot something? kick? punch? just jump?

how were the enemies?

anything you can remember can help us to identify the game.
