atari2600land strikes again with Dr. Flin and His Pills. In this game, pills are coming from the right of the screen to the left. What you do is make sure the pill color matches the hole color it goes into. If not, or it touches the sides, the pill hole becomes smaller. There are four colors of pill: red, yellow, blue and green. The green pill should be destroyed by smashing it into the wall. If a green pill gets into any hole, all three holes will become smaller.

Release notes from atari2600land:

* I made the game go a bit faster once you reach 10 points. I can change this to, well, anything below 256 points.
* Once a pill is in its correct slot and you press up or down, it does not penalize you for touching the sides. Instead, it bounces up and down until it gives you a point.
