YATC

YATC stands for Yet Another Tetris Clone but it is in fact a game in the style of Dr. Mario.

There are bugs randomly distributed on the screen that you need to destroy by combining three of a color with the two blocks pills that drop from the top of the screen that you control. It features a pill preview where you can see the next pill that will drop. You beat a level if you clear all the bugs out, you lose if you fill up the screen and can't place the next pill.
