This has been driving me crazy for months, so much so that I made this account purely to comment on this thread.
So, I remember playing this game on a nontraditional system, which was basically a portable DVD player with two wired controllers you could plug into it and a disc that contained the game I'm looking for. On this disc I remember there being Donkey Kong Jr., a Mario knock off with a red dragon/dinosaur instead of Bowser, and possibly a game involving Mickey Mouse (I was around 5-7 at this time and I'm 20 now so please excuse my blurry/inaccurate memory).
Anyways, the actual game was a very basic 8-bit platformer. It was not a side-scroller as you had to keep jumping up on platforms to get away from what I believe was a flood of some sorts. It had a sort of outdoor-castle texture vibe to it, and I remember it being consistent of the colors pink, green and blue. There may have been enemies of some sort like snakes or lizards and bugs, but again, I was very young when I played this. I also wasn't the best at video games due to my undeveloped motor skills so I'm probably only describing the first part of the game.
Please help, I feel like this was a very important piece of my childhood I'm eager to regain.
