Play Classic NES - Dr. Mario Online

Classic NES - Dr. Mario is one of those games that seems simple at first, but gets tense fast. You drop colored pills, matching them to viruses to clear the board, but the speed ramps up before you realize it. The music sticks in your head too, that same looping track from the NES version.

At first, it feels like you have all the time in the world to line things up. Then suddenly, the pills drop faster, and you're scrambling to flip them mid-air before they land wrong. The viruses don't move, but the pressure does. Mess up a few times, and the screen fills up fast.

It's still the same game from back then, just on the GBA. Some might find it too basic now, but it holds up if you like that kind of puzzle tension. Classic NES - Dr. Mario doesn't try to be anything more than what it is, and that's fine.
