Shoot, I forgot to tell you about the 3rd game I'm making. Its already 2/3 finished. You can take a look at the video below, but its already old since I implemented more features and fixed few bugs.
In short, its a puzzle action game that should be fun and for all ages and player types. Blocks are falling and your job is to make sure blocks won't fill the drop-area by matching 3 or more horizontally and/or vertically adjacent blocks of the same type/color. Then there are special blocks with special properties, some can, some cannot be removed, etc. You can also push blocks if there is enough space.
