This is a straightforward clone of the arcade game Centipede. A long slithering alien being gradually moves down a gridded playing area and must be shot out before it can reach the bottom, with the ability to move your ship in all 4 compass directions. Curiously, it doesn't seem to be possible to get a joystick to work in this, despite the chance to define keys.
Taking its title from the English word "adventure" and the squeak of a mouse; "chu", Adven'chuta is an old school adventure game, not far from Atari's old Adventure.
As a mouse, you must get around a dungeon populated by dangerous frogs and spiders. There are jars which may contain both treasures and danger, and which block the way. You have an inventory, but it can only contain one item at any time. Take care in what you pick up and leave behind. Juggling the inventory becomes a basic skill since items will block the narrow passages of the dungeon. Basic items are keys, for opening the door to the next dungeon, as well as cheese, which is good for the adventuring mouse's stamina. The dungeon must be completed within a set time or it's game over.

The semi-amusingly-named Mined-Out involves guiding a character across a screen covered with mines. He can move in any of the four main directions. At each point he is told how many of these four squares have mines in, but not the exact locations of the mines, making completion a precarious challenge. There are 8 skill levels, each with progressively more and more mines. After each level you are showed an 'action replay' of your path, as well as a full diagram of where each mine was.
In Sea Monster you control a ship out in the open seas. Beneath the waves are numerous sea monsters, many of which are attacking your ship! Your ship is located at the top of the screen, and your goal is to earn as many points as possible by shooting the various sea monsters that swim by. The deeper in the ocean the monster is, the more points it is worth. The game ends when all of your ships have been destroyed. Gameplay is for one or two players, and several game variations are available which control the speed and difficulty. Sea Monster was released by Puzzy and Bit Corporation in Europe and by CCE in Brazil.
