Formido is one of those games where you are loaded with some guns and you go shooting different things. "Things" in this case are big, ugly, alien insects.

ZRacer is a console car racing game. It has a curses based semi-graphical interface, a random track generator, editable settings, and supports hotseat multiplayer.

In Balder2D, players control small probes that shoot tiny projectiles with which they try to destroy each other. It features a 2D overhead view of the playing field. Probes may be human or computer controlled. A probe can perform the following actions: rotate, fire projectiles, "stick" to a wall, and push off of a wall. Players may rotate their probes while in flight, but the only way to change the direction or speed of flight is by firing projectiles, which gives a small kick in the opposite direction, or by running into walls or other probes.
Escluderlate is a Java game for mobiles and portable devices (J2ME). The scope is surviving inside the arena more than the computer controlled opponent(s). You have to avoid crashing on the walls that each player leaves behind. You can move your pointer using the arrows, or the keys 2(up), 4(left), 6(right), and 8(down). Escluderlate contains 21 different levels and 3 different speeds, but it's easily extendable.
Booruatsukaigaumai is a one-key desk game using OpenGL 3D scene rendering. Your task is to guide a number of red balls through 6 different levels full of blocks, holes, and gates. You have to make the balls go through as many gates as possible, which earns you the score points. However, you only have one key to control the desk tilt, which makes balls roll to the right (when the key is pressed) or to the left (when the key is released). Any other movement of the balls is controlled only by gravity and interaction with blocks, holes, and other balls. Even if the principle seems to be very simple, the game can be quite challenging.
