Years ago I inherited my wife's family's Game Gear. After a recap, and replacing the backlight, I started tracking down games to play on it. It's been great exploring a whole library of games that I skipped out on as a kid! (I was a Nintendo kid) Now I have a nice little library of carts to play on this beast of a 90's handheld.
Not the same as the Genesis version (IIRC), but I believe the Master System's game is the same as this Game Gear version.
Still a fun little platformer if you are seeing it for cheap somewhere.
