This game is an emulator for 3 of Casio's CG-5X series of solar handheld games from the years 1983-84:
* Marine Hunter CG-50
* Dandy Cowboy CG-51
* Mole Hunter CG-53
You are the commander of a defense tower, surrounded by enemy tanks. Your mission: destroy as many as possible before they destroy you. Tanks will change its color from green to yellow and red before shooting. Kill the red tanks for bonus!
You have a laser to destroy the tanks close and far away, a shield to repulse the enemy, and a radar to detect your enemies. Your laser (L) and shield (S) can get overheated so use them wisely! When your energy (E) is empty, you will be destroyed. The enemy tanks will shoot you also when you cannot see them, so watch your radar!
In Bomb Jack, the player controls Jack, who must collect all the bombs in order to complete the current round and go onto the next one. This sounds easy, right? Wrong! Making Jack's task difficult are numerous enemies such as birds, mummies, turtles, and orbs. In each round, collecting a number of bombs results in a bonus coin appearing, and collecting this coin will make the player's score increase 2 to 4 times. More often than not, the "power ball" appears, and when you collect this, you can defeat enemies and have more time to collect all the bombs. There is also the "E" coin, which gives Jack one additional life, but rarely does this coin appear. The more you progress through the game, the more difficult it becomes, as enemies travel more quickly to get you.
